memory-leak

I have CentOS 5 installed on my server. I'm in VPS server.

I have site where I have constant online ~150. First look on site looks OK. But when I go through links, sometimes I receive Out of memory PHP error. It looks like this

Fatal error: Out of memory (allocated 36962304) (tried to allocate 7680 bytes) in /home/host/public_html/sites/all/modules/cck/modules/fieldgroup/fieldgroup.install on line 100

And always, not allocated memory is very small.

In average I have 30% CPU load, 25% RAM load. So I think here is not a physical memory problem.

My PHP memory limit was set to 1500MB.

My apache error log looks like this

[Thu Sep 30 17:48:59 2010] [error] [client 91.204.190.5] Out of memory, referer: http://www.host.com/17402

[Thu Sep 30 17:49:00 2010] [error] [client 91.204.190.5] File does not exist: /home/host/public_html/favicon.ico

Past I have not met with this on my server and the problem appeared itself.

Besides this I'm receiving some server errors on mail.

cpsrvd failed @ Fri Sep 24 16:45:20 2010. A restart was attempted automagically.
Service Check Method:  [tcp connect]

Failure Reason: Unable to connect to port 2086

Same for tailwatchd.

Support tried, and can't help me...
