I'm afraid I don't. I have seen issues myself where the server would  
just die and not come up again, but never investigated it. The  
logreopen solution offers a safe and lasting fix and it even  
simplifies log rotation configuration.

Here's a very simple one that rotates ZEO server and client logs for  
a simple one-client ZEO setup, we use it for www.zope.de:

[jens at barney ~]$ cat /etc/logrotate.d/zope.de
/home/zope/zope.de/log/*.log {
         weekly
         rotate 10
         missingok
         compress
         copytruncate
}
