in reply to Apache Processes Hung on Socket Issue

Just guessing. As far as I know, Apache uses multi-threading. With multi-threading signals are not reliable. The signal is delivered to some thread, not to the specific one that waits for it. As result, the alarm won't work because the signal that it has requested is delivered to wrong thread.

Maybe Timeout parameter to IO::Socket::INET uses some other way (for example call to select).

    Actually, Apache 1.3.x which eallenvii is using doesn't use threads. It is very old compared to modern versions of Apache (current version is 2.4.4) which do allow threaded operations.

    I'm actually rather impressed that eallenvii is managing to run RHEL 5 with a newer version of perl and much older versions of Apache and mod_perl. That's quite a combination.
