Hey Will,
About the 3.4.2, what OS are you using?
Is it a self compiled version of squid?
"squid -v" will give the basic idea of the squid configurations.
I'm using a self-compiled version on Debian 6 (64bit only at the moment).

In order to verify if there is or there isn't a limit of FD that is
being reached there are couple tools that are available.
One is the /proc/ FS which can show the number of FD that is being
used by each and every one of the instances of squid.
The other one is "lsof" which you can filter using a "grep" command or
the internal options such as PID and\or SOCKETS.
the ulimit command in couple variations can indicate the basic limits:
ulimit -aH
ulimit -aS
The server I just checked has about 906 FDs open, however, looking at
the limits it can have up to 65535 open. So that's probably not directly
the issue, unless there's a select call somewhere that's failing.
Note that the squid cache-mgr interface has lots of information if
available.
Are you using cache_dir ?
I haven't looked much at the cache-mgr interface, I'll take a look at
that and see what it says. I am not using a cache_dir. In fact, no
caching is allowed at all:
cache deny all
