We have a recurring problem related the the moodle caching system.
We can fix the problem by purging all caches. However, the problem eventually returns.
Here is our Moodle environment:
3 Frontend servers running Apache 2.2.21 (FreeBSD)
The frontend servers mount the moodledata directory as an nfs mount.
1 Hardware load balancer which balances on least connections and maintains the host/server table for one day at a time.
Does anyone have any insight into how this can be resolved? One solution, although not ideal, would be to disable caching altogether but i have not been able to identify how that can be done, if possible.
Thanks in advance.
