WP-Cache Bug Strikes Back: Site Down 17 Hours
In case you visited the site a few hours back, it was down with internal server errors. Unlike last time when the site was down 36 hours, this time I knew what the problem was and as soon as I disabled Wp-cache, the site was instantly back online…
See in the image above how the site downtime occured. I had recently upgraded to the new wordpress 2.3 and decided to give wp-cache another try forgetting the site downtimes issues it had caused the previous time. The site worked fine for the last 2 days, and I thought that wp-cache and wordpress 2.3 finally worked well together. After all Wp-cache is a very fast cache module (is highly recommended for shared web hosting users), and can easily help your shared server survive a slashdotting or Digg effect better.
The problem was same as before. The cached and expired pages were of the same number and that somehow interfered with the functioning of the plugin, preventing further caching and deletion of expired pages also.
I simply disabled the plugin, emptied the cache and expired pages and deactivated the wp-cache plugin and the site was instantly back online. I hope the plugin author fixes the issue. Have you encountered a similar problem with WP-cache?

Nope, I haven’t ever had that issue. We’re currently running WordPress 2.3 as well with the latest version of wp-cache.
Your first mistake was upgrading to 2.3, which is a plugin serial killer.
I have been encountering this issue for the last one year. Wp-Cache works well, but when cached pages = expired pages – the site stops.
HiPC,
I did face this problem but initially when started using it, Guess with 2.2 but then disabling and enabling of the plugin worked again.
My number of pages were not similar but then the caching was stopped.

You are right Ashish. Once you disable and enable the plugin it works well again…. but you never know when the bug will strike again. I found out after 17 hours and fixed it; if I am on vacation, the site may be down for days!
