Hi all,

One of our customers has a mix of Windows 2000
and Linux clients. The Windows clients
run the scheduler service. The service on
these clients has to be restarted every
few days because the client hangs in the
middle of a scheduled incremetal backup.
The dsmsched.log gives no clue to what is wrong:

11/21/2003 02:24:51 Normal File-->            20,240
\\bla\c$\WINNT\VMMREG32.DLL [Sent]      
11/21/2003 02:24:51 Normal File-->           256,192
\\bla\c$\WINNT\WINHELP.EXE [Sent]      
11/21/2003 02:24:51 Normal File-->           269,584
\\bla\c$\WINNT\WINHLP32.EXE [Sent]      
11/21/2003 02:24:51 Normal File-->           193,296
\\bla\c$\WINNT\WINREP.EXE [Sent]      

And then it stops.
(The service is still running but it doesn't do anything until
it is restarted)

After an hour the session times out and the server terminates it.
The activity log on the server also contains no messages about
this client other than the time out message.

The dsmerror.log contains no messages for the time period the client
stopped
backing up.

Only the Windows clients have this problem, the Linux clients
are unaffected.

The clients are mainly 5.1.5.0 but I asked the customer
to upgrade one of his clients to 5.2.0.6
He did, but this client shows the same behavior.

The clients do not use the journal engine service or
anti-virus software.

Our server is at Version 5, Release 2, Level 1.2 on AIX 5.1

We have other customers running Windows clients, none of them has
this problem.

I'm probably going to call IBM support about this but I was wondering
if anybody here has any idea what is going wrong.

Regards,

Alexander
