Bacula expects DIR-to-FD and FD-to-SD TCP connections to persist for the 
duration of a job. If either is dropped it will cause the job to cancel. 
As a result, Bacula is not very tolerant of network problems. Since it 
appears to be the Windows Server machines dropping the connection due to 
the glitch, if there is a solution it will be in the Windows networking 
config, possibly in the NIC's driver settings. Perhaps RHEL is more 
tolerant of the glitch or perhaps it is a hardware difference in the 
NICs. Nevertheless, in general such network glitches cause problems for 
Bacula regardless of OS.
