httpd processes caught in loop

[stefan at swebase.com]

Hey

My httpd processes are caught in sbwait and eating my ram on a webserver. Does anyone know what i could do or what i should look for here because it's bringing down the server and i can't think of anything else to try. I've been checking processes, socket usage and so on but can't find anything responsible. I'm thinking a runaway script but i can't find it. 
Some server confs:
kern.ipc.nmbclusters="32768"
kern.maxproc=4096
kern.maxprocperuid=2048

and

kern.ipc.somaxconn="1024"
kern.maxfiles=65536
kern.maxfilesperproc=32768



Med vänliga hälsningar
