Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I noticed tonight my server ground to a halt. SSH, plesk and the actual site itself were all totally unavailable.

Services seemed to resume just as I got to the front of the support queueto be honest, and then the support engineer informed me there was nothing up on the system itself.

I have noticed this kind of beahiour before, and it seemed to be centred around the dir that mod_cache uses to store the actual cache hierarchy. I went in and did an "htcacheclean" on a directory that was initially ~52MB when i dialed in and just under 1MB once I'd run the cache clean command.

Anyone got any experience of any of this.

I have a cron setup now that should hopefully alleviate the problem, but wouldn't mind a bit more info as to exactly what the hell was happening....

cheers all!

mod_cache is an Apache module, not a PHP module. –  Charles Mar 22 '11 at 22:47
    
Thanks. that comment really helped pin down the issue. –  BizNuge Mar 22 '11 at 23:17
    
Proper classification of problems does help, my friend. So does posting in the right place. This should be posted on ServerFault. I'm out of close votes at the moment, otherwise I'd have previously suggested that. –  Charles Mar 22 '11 at 23:27
    
Close votes? Apologies as i'm quite new to actually posting on stack. I couldn't even create a mod_cache meta tag for this. Move it to serverfault if you can, and feel it's more appropriate though. –  BizNuge Mar 22 '11 at 23:58
    
Check out this page -- eventually you can vote to close questions and possibly move them to other sites. It takes five votes or a real moderator to perform a move. –  Charles Mar 23 '11 at 0:00
