Hi Everybody I have recompiled Squid the way i saw in one of the how to. this is what i did 1)I uninstalled Squid 2) #ulimit -HSn 8192 #then recompiled squid with --with-maxfd=8192 then in my starting squid script i have added ulimit -HSn 8192 But still it shows the same number of file descriptors File descriptor usage for squid: Maximum number of file descriptors: 1024 Largest file desc currently in use: 939 Number of file desc currently in use: 929 Files queued for open: 1 Available number of file descriptors: 94 Reserved number of file descriptors: 100 Store Disk files open: 19 IO loop method: kqueue There is something fishy about it coz my cache is only 1.1G . and moreover there is a file squid.core in my /etc/squid and i do not understand its porpose. i searched for it online but still i did understand it. Is my squidclient giving me stale results. I had even cleaned the cache before reinstalling squid. Is there some different way to increase the file descriptors in OpenBSD. Kindly Help.
