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? Watch out for the ulimit in the shell launching squid. -- /kinkie
