[Zope-dev] hanging zeo clients

We have one ZEO server that handles 3 FileStorages and 8 ZEO clients
connecting to the ZEO server.
Sometimes a client hangs and does no longer handle incoming connections.

The ZEO server log shows in such a case, that the (hanging) client
initiates a new connection

  2006-11-12T10:30:39 INFO ZEO.StorageServer (3958) new connection
('10.x.x.x', 32803): <ManagedServerConnection ('10.x.x.x', 32803)>

If I'm correct, the next that should happen is a log entry from the
ZEO server that he received a handshake from the client. Something

  2006-11-12T11:12:46 INFO ZEO.zrpc.Connection(S) (10.x.x.x:36805)
received handshake 'Z303'

This never happens. I have to restart the client.

Has anyone an explanation for the hanging clients?

(We're using Zope-2.8.8, Python-2.4.2)
