OK. Do you have more than one ZEO client? If not,
I'd reevaluate whether you need ZEO at all.
(It's great for zopectl debug on a live system, but otherwise it does
nothing but add overhead if you're not using it to run multiple
Zopes. But you probably knew that.)

OK. It should be pretty obvious if you were hitting a limit.
I don't think it's possible on linux to run out of memory without the
kernel complaining somewhere in /var/log.

Well, as I said, it's very unlikely to have any impact on
If I were in your shoes the first thing I'd do is bump up the log levels
on both zope and zeo to BLATHER. Adds overhead I know, but you need to find
the problem somehow... it's a weird one, I've never seen zope
restart "for no reason".
