Thanks for the advice. Entropy does sound like a plausible reason,
although I have plenty of other crypto apps and I didn't notice any of
them hanging in this way. The server in question is a 'user mode linux'
virtual server, and there has been mention of lack of entropy as a
possible problem with this setup.
I'll keep an eye on entropy_avail if them problem happens again. I
assume a low number means badness?
