just for case anyone runs into similar problem - the issue was the firewall
between clients and storage daemon was timing out the inactive tcp session
after certain period. what happens is when the job starts it establishes the
tcp session with the storage daemon and then it starts the scripts on the
client. only when the script is finished the data are sent over the tcp. if the
script takes too long the tcp stays established but not active for the whole
period so it can time out on the firewall and later when bacula attempts to use
the tcp which it thinks is still established it fails.
I was trying to use "Heartbeat Interval" together with tweaking tcp keepalive
time on system level but that doesn't seem to be enough for my firewall (that's
another problem though)...
cheers,
Antony.
