I have been running sup-sync on a new mailbox, and it tends to get
partway through and then die, but not in the same place each time.
Twice, the error has been like
/var/lib/gems/1.8/gems/sup-0.7/lib/sup/crypto.rb:162:in ``': Cannot allocate memory - /usr/bin/gpg --quiet --batch --no-verbose --logger-fd 1 --use-agent --verify /tmp/28751-0-redwood.signature /tmp/28751-0-redwood.payload 2> /dev/null (Errno::ENOMEM)
followed by a backtrace. Another time, it was just
zsh: killed /var/lib/gems/1.8/bin/sup-sync --all-sources
I monitored the sup-sync process the last time. It's memory use grew
slowly, and the process died at around 64M of virtual memory. I don't
have any memory limits set. Is it possible that sup-sync or ruby uses
some itself? Any other ideas?

I forgot to mention, this was the latest release (0.7) installed with
gem. I just tried the current git mainline (clearing all my .sup state
first), and it got through my whole mailbox without a problem.

Very mysterious. Sup-sync doesn't do anything fancy with memory; it's a
fairly straight-forward Ruby script. Maybe one of the C extensions (like
Ferret) has a memory leak.

Evey more mysterious. The differences between these two versions are
trivial:

I'm at a loss.

I cannot reproduce the problem anymore, but as far as I know, nothing
changed on my system (other than the inbox I am testing with evolving
routinely). sup-sync from the 0.7 gem now runs to completion and never
uses more than ~36M virtual memory (before it got up around 60M before
crashing). It doesn't seem possible that the git copy of sup affected
the installed gem. So I'm at a complete loss too.

Let's just pretend this never happened.
