We are seeing spontaneous restarts of Zope with no indication in any of the standard Zope logs. Looking at the ZEO log indicates that the restarts of Zope are due to a lost connection between Zope & ZEO but with no other information. The logging level is set at the distribution default (INFO).
The restarts are a huge problem because session variables are not persistent and so all of the user state they contain is lost on restart. In our statful implementation, this is a major problem. I want to adjust the configuration so that the Zope/ZEO connection is stable.
In our configuration, Zope and ZEO are linked via localhost on a distinguished port.
I've Googled about looking for some infomation about tuning the ZEO/Zope interface, but have found little real information. Some additional log detail would be helpful.
Once established, connections between ZEO server and Zope should be totally stable. I'd investigate network or firewall problems, and I'd start by using a network trace to find out what's happening at the TCP and IP levels.
