Hi
There could be a problem with james 2.2.0 in a High Avaliability
environment.
We set up 2 james instances to work at the same time on the same database
(using a failover connection string).
There is a load balancer which every few seconds checks if the pop3 server
is alive, without closing properly the pop3 session.
Every time the check happens we get in the pop3server logs an error message
"Connection reset".
This is the stacktrace:
26/02/07 14:43:27 ERROR pop3server: Exception during connection from
<ip_address> (<ip_address>) : Connection reset
java.net.SocketException: Connection reset

We thought it wasn't harmless, but after a while (more or less an hour) the
system crashes.
At the moment the problem happens even if there is only one james instance
up and running, i.e. it's not a concurrency problem.
Any help will be REALLY appreciated.
Thanks
Marcello
