I've got a 7-client ZEO cluster. The client machines are Celeron's and the ZEO server is on a dual XEON. All communication is over a private network with a switch in the middle.
Lately I have been getting ClientDisconnected errors more often than I would like. restarting the offending client or the zeo server is a temp solution.
We have had similar problems. Someone on the list asked whether we have some NAT (Network Address Translation) agent in between. We had... Such NAT agents close connections when unused for some time in order to protect their resources. The timeout of our NAT agent was 30 min. Our solution: send a keep alive message every 20 min. -- Dieter
