We're fronting two Zopes with Pound for load balancing. I can't see there would be any connection with this error. But I mention it in case there's a pattern.
Also, the database came from 2.7.0 and an earlier python. This looks like resource starvation to me. The servers run for an hour or two this problems shows up, becoming worse for a while, then we need a restart.
I'm try to debug it tomorrow. What would you look for? Any tips for resource monitoring?

It's intermittent at first, then back-to-back.
Following thread leads me to look for memory shortage. But I'd expecta
different message in that case.

This thread seems to suggest such messages (in different context)
canbe ignored. But I can't do that. This is a symptom of a bigger
problem.

Has anyone seen this in these circumstances?
