Description Paul P Komkoff Jr 2005-09-12 11:01:47 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; ru-RU; rv:1.7.10) Gecko/20050717 Firefox/1.0.6

Description of problem:
When squid ./configure script runs, it trying to detect maximum number of filedescriptors it can open. By default, ulimit is set to 1024.

1024 may be suitable for single-user deployment, but absolutely unsuitable for 1200 hosts behind proxy. For this situations, more suitable value is, perhaps, 16384.

Version-Release number of selected component (if applicable):
squid-2.5.STABLE9-8

How reproducible:
Always

Steps to Reproduce:
rpmbuild --rebuild and see messages it emits
Ctrl-C in progress and see SQUID_MAXFD set to 1024 in autoconf.h

Something like this will be enough I think

Comment 2 Martin Stransky 2005-09-19 08:13:39 UTC

Please, route this issue to upstream, http://www.squid-cache.org/ and file the
request here. I don't want to change this default value for Fedora only. And If
you have to manage a large site, you surely don't use the default values but you
do some tuning.

Comment 3 Paul P Komkoff Jr 2005-09-19 11:53:56 UTC

Of course I'm doing some tuning! Rebuilding squid with maxfd patched, and
putting it in exclude= line of my yum.conf to avoid "official" broken package
from slipping into server.

Seriously, I wrote mail to "upstream". But what we have in fedora is just build
system deficiency on the one side (one cannot set ulimit -HSn 16384 prior to
build), and you, claiming this bug as a feature, on the other.
