We have seen the "disconnect" problem in connection with heavy disk
traffic as mentioned in previous messages to this list (probably
starvation of the messages from the failover partner).

We have also seen the problem of the servers not reconnecting, and I
believe I have a reproducible bug here - just need to test it on
Linux also to be sure that it's not a FreeBSD specific bug.
