I already increased the memory from 256M to 768M because of that, so I am not confident this will help. * [@deliciousbrains](https://wordpress.org/support/users/deliciousbrains/) The entire site is about 4.5GB with +/- 7000 original images. Each images has 5 generate images + original. Each image isn’t more then 1.2MB I use smush for image processing. * My pages with images are set in lazy load slide show. Only two images load when you visit the page, then each image preloads as you go thru the slide show. So there really isn’t a page where you get dumped with 100’s of images at the same time. * I have tried to trigger the error myself, but I am not having success. It’s almost like a magic trick. I can do something in admin and it pups up. Then when I try to replicated it nothing! Same thing with front end. I look through pages and it will show up. Minute latter when I am replicating the steps nothing. * Thread Starter [Seath](https://wordpress.org/support/users/seath/) * (@seath) * [2 years, 6 months ago](https://wordpress.org/support/topic/memory-problem-9/#post-17097488) * [@dbisupport](https://wordpress.org/support/users/dbisupport/) Still there ….. * ```wp-block-code Oct 03, 14:28:53 [CRITICAL] : Allowed memory size of 1073741824 bytes exhausted (tried to allocate 20480 bytes) Oct 03, 14:28:53 Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 20480 bytes) in /wp-content/plugins/amazon-s3-and-cloudfront/classes/items/item.php on line 751 Oct 03, 14:27:39 [CRITICAL] : Allowed memory size of 1073741824 bytes exhausted (tried to allocate 20480 bytes) Oct 03, 14:27:39 Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 20480 bytes) in /wp-includes/functions.php on line 650 ``` * Plugin Author [Delicious Brains](https://wordpress.org/support/users/deliciousbrains/) * (@deliciousbrains) * [2 years, 6 months ago](https://wordpress.org/support/topic/memory-problem-9/#post-17098582) * The line of code where it’s having issues relates to unserializing the `extra_info` field from a `wp_as3cf_items` database record. * This suggests to me that something has maybe saved a huge lump of data to a ` wp_as3cf_items` record’s `extra_info` field, or there’s something weird going on with the `unserialize()` function, maybe due to some wayward data saved to the `extra_info` field. * I would suggest that the first thing to check is whether there are any `wp_as3cf_items` records that do not have the expected data. * Try running the following SQL query to see how many records don’t have the expected data format: * ```wp-block-code SELECT COUNT(*) FROM wp_as3cf_items WHERE extra_info NOT LIKE '%__as3cf_primary%' ; ``` * Adjust as necessary depending on your database’s table prefix. * If you get a count of more than 0, then there’s something weird going on and you should investigate which records are affected, and why. * If nothing comes back, then you’ll need to look elsewhere for the cause, assuming you can’t see any obviously weird records in the `wp_as3cf_items` table. * In that scenario, check out any plugins that have recently been added or updated, maybe temporarily deactivate them one by one until the problem is resolved, and switch to a stock WordPress theme. * Ideally do this investigation on a clone of the site that also has the issues( I’m assuming this is a production site issue). * -IJ * Thread Starter [Seath](https://wordpress.org/support/users/seath/) * (@seath) * [2 years, 6 months ago](https://wordpress.org/support/topic/memory-problem-9/#post-17099364) * The count came as 2233 * I will look in the records but there is “Showing rows 0 – 24 (4519 total, Query took 0.0002 seconds.)” And I am not sure what to look for.

As such, here’s the steps to try and fix the issue: 1. Go to WP Offload Media’s settings page and look for an upgrade notice at the top. 2. If you see one, presumably its not running properly as it’s been a good while now. Please ensure your site’s cron is running, as upgrades are purely run via cron: [https://deliciousbrains.com/wp-offload-media/doc/cron-setup/](https://deliciousbrains.com/wp-offload-media/doc/cron-setup/) 3. If you do not see an upgrade notice, then you’ll need to tell WP Offload Media to re-run the last upgrade routine. To do that, update the options record with option_name = “tantan_wordpress_s3” so that the bit that currently says: `s: 17:"post_meta_version";s:2:"12";`, now says `s:17:"post_meta_version";s:2:"11";`. 4. Be very very careful about updating that `tantan_wordpress_s3` record, it is a horrid serialized value format that requires the string length indicators to be accurate. Probably the safest way to update that `tantan_wordpress_s3` record is with my WP Table Pixie plugin as it fixes minor serialized value problems when you save a record: [https://wordpress.org/plugins/wp-table-pixie/](https://wordpress.org/plugins/wp-table-pixie/) 5. If you find that the `post_meta_version` is already something less than `12`, then do not update it to `11`, but instead go fix your cron and check why the notice was not being shown in WP Offload Media’s UI! 😱 * Hopefully that’ll get the upgrade routine(s) running and you’ll eventually see that all the as3cf_items records are working again. * –IJ * Thread Starter [Seath](https://wordpress.org/support/users/seath/) * (@seath) * [2 years, 5 months ago](https://wordpress.org/support/topic/memory-problem-9/#post-17200251) * My cron is ruining. I did updated `s:17:"post_meta_version";s:2:"12";`, to `s: 17:"post_meta_version";s:2:"11";` so hopefully this will fix the problem. * Here is the diagnostic info. * ```wp-block-code site_url(): https://site.net home_url(): https://site.net Database Name: my_database Table Prefix: xxx_ WordPress: 6.4.1 Web Server: Apache PHP: 8.2.12 MySQL: 5.7.44 ext/mysqli: yes PHP Memory Limit: 1024M WP Memory Limit: 1024M Memory Usage: 12 MB Blocked External HTTP Requests: None WP Locale: en_US Organize offloads by month/year: Enabled WP_DEBUG: No WP_DEBUG_LOG: No WP_DEBUG_DISPLAY: Yes SCRIPT_DEBUG: No WP Max Upload Size: 8 MB PHP Time Limit: 60 PHP Error Log: /home/site/logs/site_net.php.error.log WP Cron: Enabled fsockopen: Enabled allow_url_fopen: Disabled OpenSSL: OpenSSL 1.1.1w 11 Sep 2023 cURL: 8.4.0 Zlib Compression: Enabled PHP GD: bundled (2.1.0 compatible) Imagick: Disabled Basic Auth: Disabled Proxy: Disabled Total Media Items: 6,878 Total Offloaded Media Items: 4,642 Total Not Offloaded Media Items: 2,236 Media Library Items: 6,878 Offloaded Media Library Items: 4,642 Not Offloaded Media Library Items: 2,236 Number of Image Sizes: 6 Names and Dimensions of Image Sizes: thumbnail (350x250) medium (800x500) large (1500x1000) 1536x1536 (1536x1536) 2048x2048 (2048x2048) WP_CONTENT_DIR: /home/site/public_html/wp-content WP_CONTENT_URL: https://site.net/wp-content UPLOADS: Not defined WP_PLUGIN_DIR: /home/site/public_html/wp-content/plugins WP_PLUGIN_URL: https://site.net/wp-content/plugins AS3CF_PROVIDER: Not defined AS3CF_BUCKET: Not defined AS3CF_REGION: Not defined AS3CF_SETTINGS: Not defined Local URL: https://site.net/wp-content/uploads/2023/11/example.jpg Offload URL: https://cdn.site.net/WP/wp-content/uploads/2023/11/14050941/example.jpg OME Metadata Version: 11 Custom tables: xxx_as3cf_items: Ok Storage Provider: Amazon S3 Use Server Roles: Off Key File Path: N/A Access Keys Set: Yes Access Key ID Define: DBI_AWS_ACCESS_KEY_ID Secret Access Key Define: DBI_AWS_SECRET_ACCESS_KEY Bucket: cdn.site.net Region: us-west-2 Block All Public Access: Disabled Object Ownership Enforced: No Offload Media: On Remove Local Media: Off Enable Add Prefix to Bucket Path: On Custom Prefix for Bucket Path: WP/wp-content/uploads/ Add Year & Month to Bucket Path: On Add Object Version to Bucket Path: On Delivery Provider: Other Deliver Offloaded Media: On Use Custom Domain Name (CNAME): On Custom Domain (CNAME): cdn.site.net Force HTTPS: Off Active Theme Name: site Active Theme Version: 1.1.0 Active Theme Folder: site Active Plugins: 301 Redirects Pro (v6.15) by WebFactory Ltd ACF: Better Search (v4.2.0) by Mateusz Gbiorczyk AIOWPS Country Blocking Addon (v3.0.6) by Peter Petreski, WPSolutions-HQ, Site Scanners, Accessibility Widget (v2.1) by Lorna Timbah (webgrrrl) Advanced Custom Fields PRO (v6.2.2) by WP Engine All In One WP Security (v5.2.5) by All In One WP Security & Firewall Team Art Of Design Real Estate (v1.0.0) by Art Of Design BBQ Firewall (v20231026) by Jeff Starr Blackhole for Bad Bots (v3.6.1) by Jeff Starr Classic Editor (v1.6.3) by WordPress Contributors Classic Widgets (v0.3) by WordPress Contributors Contact Form 7 (v5.8.2) by Takayuki Miyoshi Dashboard Widgets Suite (v3.4.2) by Jeff Starr Error Log Monitor (v1.7.7) by Janis Elsts Flamingo (v2.4) by Takayuki Miyoshi Koko Analytics (v1.3.3) by ibericode List Custom Taxonomy Widget (v4.1) by Nick Halsey Nobs • Share Buttons (v2.3.2) by Geoffrey Crofte Post SMTP (v2.8.2) by Post SMTP PublishPress Capabilities (v2.10.1) by PublishPress Smush (v3.15.0) by WPMU DEV Two Factor Authentication (v1.14.17) by David Anderson, original plugin by Oskar Hane and enhanced by Dee Nutbourne UpdraftPlus - Backup/Restore (v1.23.12) by UpdraftPlus.Com, DavidAnderson VA Simple Expires (v1.0.6) by KUCKLU & VisuAlive WP Armour - Honeypot Anti Spam (v2.1.5) by Dnesscarkey WP Better Permalinks (v4.1.1) by Mateusz Gbiorczyk WP Crontrol (v1.16.0) by John Blackbourn & crontributors WP Offload Media Lite (v3.2.5) by Delicious Brains WP Rollback (v1.7.3) by GiveWP.com WP Sitemap Page (v1.9.2) by Tony Archambeau WP Statistics (v14.2) by VeronaLabs WP Table Pixie (v1.2.1) by Ian M.
