Has happens for a couple of days at a time, seems to be traffic related, no apparent pattern available from log files, Firewalling off certain Internet address ranges seems to help.

 * site drives a public web site)
 * if it matters, the top level application is "Plone"
 * system is running other applications, nothing else seems to be effected
 * zope runs behind apache2

I attached strace to it and this is what happens when it crashes;

 accept(3, {sa_family=AF_INET, sin_port=htons(39771), sin_addr=inet_addr("127.0.0.1")}, [16]) = 21
