There is no power management on our servers :-D
I just ran some tests this afternoon, I create a new bacula server
with lenny / bacula 2.4.4, and downgrade the client to 2.4.4, to
be sure that all was fine with the same fileset, etc.
The test was OK, no problem, the job ran fine.
Than I tested again with our production server (5.0.3) and
the 2.4.4 client => network error, failed job
I upgraded the test bacula server to squeeze / bacula 5.0.2,
and still the 2.4.4 fd on the client => No problem !
So it seems that the problem is clearly in "network hardware" on the
server side.
We will do some more tests on the network side (change
switch port, change wire, see if no firmware update is available...),
but now I really doubt that the problem is in bacula, nor it can be
resolved in it.
The strange thing is that the problems are only observed with win32
clients. Perhaps the Windows (2003) TCP/IP stack is less fault tolerant than
the linux one in some very special case ?
