Funny you should mention that. We just had a similar thing happen to us 
this morning. We have an installation of Zope 2.1.6 running on Red Hat 
Linux 6.0 on an old 486/66 machine (a prototype serving some intranet 
content). We aren't doing any database connections on it (through Zope, 
that is), but we are running Squishdot (which is the main application in 
terms of usage on this particular machine). Zope is running behind Apache 
1.3.9, and I noticed that multiple instances of Zope.cgi started up to 
service incoming requests, but apparently Zope wasn't responding. I just 
restarted Apache and everything was fine again.

Is this a known problem with Zope that has been addressed in 2.2?

Thanks.
