Yes, it's a memory problem that has happened twice now and requires a
restart of the VPS. I believe the first culprit was an Apache module,
Mod_survey, doing a data export; the second, Namazu indexing some
Mailman archives. I think you're right, I'll have to add more RAM, but I
was hoping not to spend the extra $10/month ;) Tech support believes
Mailman is the problem because it was the only thing showing memory use
from ps -aux.

Are you aware of any hosting providers that use Xen?

Thanks for the info,
