Re: [squid-users] query about --with-filedescriptors and ulimit

Umm your reply confused me further! :) Please see below inline. ----- Original Message ----- > From: Amos Jeffries <squid3_at_treenet.co.nz> > To: squid-users_at_squid-cache.org > > On 14/02/2013 10:12 p.m., Amm wrote: >> >> I compiled squid using --with-filedescriptors=16384. >> >> So do I still need to set ulimit before starting squid? > Yes.

If squid obeys the smaller limit shoudn't it report "Available number of file descriptors" to max 4096?

I have SELinux disabled. I just got this: 2013/02/14 15:07:08 kid1| Attempt to open socket for EUI retrieval failed: (24) Too many open files 2013/02/14 15:07:08 kid1| comm_open: socket failure: (24) Too many open files 2013/02/14 15:07:08 kid1| Reserved FD adjusted from 100 to 15391 due to failures 2013/02/14 15:07:08 kid1| '/usr/share/squid/errors/en-us/ERR_CONNECT_FAIL': (24) Too many open files 2013/02/14 15:07:08 kid1| WARNING: Error Pages Missing Language: en-us 2013/02/14 15:07:08 kid1| WARNING! Your cache is running out of filedescriptors How to know number of FD open when this error occurred? I want to know if it was 1024 or 4096? Did squid automatically handle it? Why does it say 15391 instead of something below 4096? Or 15391 is right and expected and I do not have to set ulimit before squid starts?   >> So back to my question: >> If I am compiling squid with --with-filedescriptors=16384 >> do I need to set ulimit before starting squid? >> >> Or does squid automatically set ulimit? > > Yes. Yes was for that "I have to set ulimit before starting squid" OR Yes was for that "squid automatically sets ulimit and i do not have to do anything" > Amos Thanks for your quick response. Regards Amm
