I have read the FAQ.
[root@cache1 squid]# ulimit -n
1024
[root@cache1 root]# cat /proc/sys/fs/file-max
  104854
[root@cache1 root]# ulimit -HSn 100000
[root@cache1 root]# ulimit -n
100000

Then I edit the /etc/squid/squid.conf and change the max_open_disk_fds:
  max_open_disk_fds 100000

[root@cache1 root]# /etc/init.d/squid restart
[root@cache1 root]# cat /var/log/squid/cache.log |grep descriptors
  2004/10/14 16:00:18| With 1024 file descriptors

I understand that squid needs to be recompiled, could someone help me
with the parameters for recompiling squid? I'm trying to give
transparent cache for a lot of users.

In the mean while, I reduced the users conected to squid, and the
"WARNING! Your cache is running out of filedescriptors" doesn't appeared
anymore.... but I still have users that don't get a response from the
transparent cache.....

Thanks,
Alejandro
