I would take a look at File descriptor allocation in the cachemgr.cgi and discover what is going on with your file descriptors.

Im baffled. Somethign doesnt jive. And the cpu spike to 6.0, with that many sockets opened. so i set ulimit to 999999 (1 million basicaly) and rebuild squid again. According ot cache.log it locks at 32768 file descriptors, it wont load the 9999999, it appears a hard limit in deed! Anyway netstat -vatn shows only 3352 open sockets right now but z19 isnt repsonding well, and within a few minutes i stoped it and went back to http mode... what should i do the next?
