Try setting "Maximum Network Buffer Size" to 32768 in both the storage
daemon and client configs. It looks like something doesn't like the
default 65536 buffer size.
Also, a backup job can run a long time, and Bacula keeps the TCP
connections open the entire time. Make sure a switch isn't timing out a
TCP connection when it shouldn't. You may also want to look up the
"Heartbeat Interval" setting in the Bacula docs.
