Hi,

I had to start squid in prodcution network and to my supprise, it
worked for about 1 minute, and then the messages bellow started
flowing. In the WCCP router, more 10000 requests were forwarded
after less than 1 minute!!!! (192.x.x.x/19 network)

I noticed that cache server ran out of file descriptors, How to fix this ?

How do I tune ip_conntack table ? My actual max value is:
[root@cache ~]# cat /proc/sys/net/ipv4/ip_conntrack_max
65536

Thanks for your answers

Dan
