Currently I'm using gcc 2.8.1, but I can certainly use for example gcc 2.7.2.3
or even acc (Sun Commercial one). Today, I inserted the following lines into the
/etc/system file:

set maxusers=256
set rlim_fd_max=1024
set rlim_fd_cur=512

Let's see if there is any difference. -DUSE_POLL didn't seem to solve the problem ...

Yes, this is plain Squid 1.1.20 + retry patch. I have tried without the retry
patch as well without any change in Squid's behaviour.
