We ran into this issue when we replaced all our iptables firewalls with Juniper 
SSG devices.  Check the timeout values for the service you defined on your 
juniper for your bacula ports, the juniper will have a default session time, we 
found the juniper closes the connection often, and ended up having to disable 
the timeout feature for the bacula services.

This looks suspiciously close to 7200 seconds which is the default 
tcp_keepalive_timeout for most Linux distros.

Have you tried using the bacula dir / fd heartbeat feature? Is there a firewall 
(iptables?) involved somehow?

I've set Heartbeat = 30 in the director and yes there is a firewall between dir 
and fs, not iptables but a juniper, the firewall of the company.

Have you tried lowering the tcp_keepalive_timeout on both ends?

# echo 300 > /proc/sys/net/ipv4/tcp_keepalive_time


I'll try this.

The heartbeat also needs to be on the client config, too.  I have much fewer 
timeouts, not completely free of them, though.
