We have Varnish -> nginx -> php-fcgi

Since yesterday, and from time to time we get a blank page from the php-fcgi. And an increased memory consumption.

We have changed php-fcgi to die each 100 requests instead of 1000, and this helps us to improve the situation.

The problem is that we can't see anything on the php error.log. Is there a similar tool to Extended Server Status so we can check wich urls are being server, or memory consumption, etc...?

I suppose it must be done directly to the php-fcgi, as nginx knows nothing about what's happening @ php process.

Anyideas on how to find the culprit?

Thnx in advance for your help!!!
