Server unresponsive - Any ideas?

[kermit2]

Are you able to identifiy if it's particular pages that take a long time to load?

Obviously there are things like xcache and eaccelerator, but with PHP times that high there must be a bigger underlying problem. Might be worth running vmstat and seeing what's going on when the pages are taking a long time to load

Please start by posting in the Server Configuration forum on vB.com.

I did, when Lynne told me so.

Its not particular pages. It happens randomly, on random pages and it happens more frequently during peak hours.

Its usually 1,3GB - 1,8GB (out of 6)

Can you copy the board to a test environment enabling the PHP error reporting in case there's something wrong ?

Wouldn't that show up in the error logs?
Also wouldn't it occur in specific pages, all the time, if that was the problem?

cant you post the phpinfo page ?

mine looks like this - http://disputeclaims.org/phpinfo.php

I was asked for this at vb.com as well but I was hesitant to post it due to security reasons. Anyway, since I seem to be the only one with similar hesitations, here it is:

This might be a shot in the dark but...

vBulletin 3.7.x supports PHP 5 without any problems, though you may need to disable strict mode for MySQL, see HERE on how to enable 'force_sql_mode'.

[kermit2]

You might want to run vmstat for a while, or keep an eye on things with top or ps too. If you add:

if(IPADDRESS == '1.2.3.4') {
$config['Misc']['debug'] = 1;
}

, to the bottom of your config.php (obviously changing 1.2.3.4 to your IP address), you'll get some debugging info too, in particular how long each mysql is taking, and how long PHP spent running

[Lea Verou]

Jesus, I know how to enable debug mode for my IP address! LOL!
And I have done it already, nothing insighful.

I see no php cache installed. I recomend you install xcache. Also make sure you have gzip disable in vbulletin you have mod_deflate installed.

so your saying we can go to vb.com and ask them to optimize our server - would there be any benefits for this as im on a dedicated server and tbh never really throught of having it optimised for vb.
