I'm running one of the nightly 3.2.0.16. I've always built squid 3.x
"--with-filedescriptors=16384".
Squid Cache: Version 3.2.0.16
configure options: '--prefix=/usr/local/squid' '--build=i686-apple-darwin'
'--mandir=/usr/local/share/man' '--with-large-files' '--disable-ident-lookups'
'--disable-dependency-tracking' '--enable-filters'
'--enable-removal-policies=heap,lru' '--enable-delay-pools'
'--enable-multicast-miss' '--enable-default-err-language=templates'
'--enable-fd-config' '--with-filedescriptors=16384' '--with-dl'
'--enable-ltdl-convenience' '--enable-http-violations' '--enable-build-info'
'--enable-log-daemon-helpers' '--enable-auth-basic=PAM,NCSA,LDAP,NCSA'
'--enable-auth-digest=password'
'--enable-external-acl-helpers=ip_user,ldap_group' '--enable-ssl'
'--enable-internal-dns' '--disable-eui' 'build_alias=i686-apple-darwin'
So it's very surprising for me to see "WARNING! Your cache is running out of
filedescriptors" in cache.log after I pumped a few hundred of connections
through recently.
According to squidclient -r -l localhost -U manager -W passwd mgr:info |grep
'file descr', my instance of squid 3.2.0.16 only has 256 file descriptors:
Maximum number of file descriptors: 256
Available number of file descriptors: 221
Reserved number of file descriptors: 64
I can resolve this easily by setting "max_filedescriptors ####" in squid.conf.
However, this is supposedly a "Squid 2.7+" feature, according to
"http://wiki.squid-cache.org/SquidFaq/TroubleShooting#Running_out_of_filedescriptors";.
It's not clear whether that's inclusive of Squid 3.x, which is a separate
branch from squid 2.6 in my understanding. The other question is why the
configure option "--with-filedescriptors=16384" has no effect or stopped taking
effect in Squid 3.2.0.16. Is this just an isolated one-off incident?
