W3 Total Cache
Cron jobs getting stuck with object and database caching enabled (4 posts)

    I write this somewhat sheepishly since I love this plugin. W3 Total Cache is a remarkable piece of work and has been a true lifesaver for my site.

    The problem I have been having is with cron jobs getting stuck in the queue. I noticed three plugin cron jobs getting stuck in particular.

    1. WordTwit Pro: scheduled tweets fail
    2. GDPress Tools Pro: scheduled backups fail
    3. Disquus Commenting System: scheduled comment sync fails

    I did some troubleshooting and narrowed down the issue as W3 Total Cache's database and object caching features. When I disabled the database and object caching features, the cron job queue returned to normal operation.

    I am not sure what about my server environment, these plugins and W3 Total Cache's database and object caching is conflicting, but I have Xcache enabled as the Opcode caching method. I have yet to try APC or Memcache to determine if I can replicate the errors under those conditions. For now, I have disabled database and object caching.

    Even so, in my book, this is still the best WordPress caching plugin out there - and it's free! I would appreciate any advice as to how to resolve this one issue.

    Did you file a bug report from the Support page in the plugin?

    I didn't file a bug report because I am now using Quick Cache, which does a great job for what I am looking for.

    WP Cron is improving in the next release, you may want to re-try W3TC after the next release.
