OK, let me tell you what is happening when I put "ulimit -Sn 2048" (or any
value more than 960) command in /etc/init.d/squid script
I restart the Squid. and then ---
tail -f /usr/local/squid/var/logs/cache.log |grep descriptors
2005/01/07 13:37:20| With 960 file descriptors available
but form command "ulimit" command shows the following:
ulimit -SHn ---- the value is 1024
ulimit -n ----- 1024
So what is my mistake here ?
Why squid cache shows 960 but not 1024 or even 961 :)
Thanks again for the answers
