I seem to remember someone on here having this problem previously.
Bacula daemons all set socket option SO_KEEPALIVE to keep the
connections from timing out, but a switch in between was not properly
honoring the TCP keepalive. When the switch times out the connection,
both FD and DIR then think the other side closed the connection.
However, Michael mentioned that on the second scenario all servers are
on the same hypervisor and there is no switch. Maybe the place to start
is to move the failing VM to the other hypervisor and see if it still
fails. Perhaps there is some difference in the VMWare configs.
