Ah yes, you are right. I just checked the spec file --with-filedescriptors=16384 Earlier I didnt check spec file because EXACTLY same spec file was used for 3.2.1 and it was using max_filedescriptor setting even when compile time 16384 was mentioned. Its strange though. Anyway atleast the root cause has been found Apparently its hardcoded in Fedora repositories. (currently line 156) http://pkgs.fedoraproject.org/cgit/squid.git/tree/squid.spec?h=f18 I suppose I will leave that as default as I do not want to change the spec file. >________________________________ > From: Amos Jeffries <squid3@xxxxxxxxxxxxx> >To: squid-users@xxxxxxxxxxxxxxx >Sent: Wednesday, 24 October 2012 6:44 PM >Subject: Re: 3.3.0.1 warning on reload - max_filedescriptors disabled > >On 24/10/2012 8:00 p.m., Amm wrote: >> looks like somewhere this number 16384 is hard-coded in 3.3.0.1 > >It is only hard-coded in your particular build because of > >Amos
