Hi Jim;

We've experienced this same issue on our Win2K / NW server.  If you cross 
reference the daemon.log with the savegrp.log you should
notice that the save set actually completed hours prior to the timeout 
condition being met.  That's what we used to encounter.  Our
solution was to update from 6.1.1 to 6.1.3.  This seemed to resolve the issue 
in our case.  The logs are the important part of the
trouble shooting though.  It appears that NW has a problem in keeping track of 
what it's doing.  :)

Good luck,

Carter

In activity timeout is at 30 minutes.  I have multiple clients defined and 
several of them were still awaiting backup.  Finally
paralellism is set to 4, so even if one client was slow, should the other 
clients keep the group busy and stop it from timing out?

None of the clients have really big volumes (i.e 100GB max and only 7GB used).  
Network is Gb on fast server with SAN attached disk.

Anything else?

Look if the occurrence is matching with incr/differential backup schedules on 
big volumes : I experienced more than once that
incr/differential backups of big volumes to cause inactivity time-outs and 
backup to be aborted, networker not receiving data fast
enough because save was walking down the big volume retrieving modified files 
or because disks were I/O saturated (caused by
Anti-Virus Scan).

The same trouble can also be caused by big files from {slow} client, networker 
not getting CFI updates fast enough in the time range
and then times-out.

You can give a try to increase group inactivity to avoid that problem.

HTH,

Thierry

What is the cause though?  It happens from time to time and it really ticks me 
off.  I have multiple "incomplete savesets" listed
under details.  What is the best way to troubleshoot this type of problem?

Cheers,

look for the 'save' process on the client side and kill it (Unix) or stop it 
(Windows). I had this issue lots of time.

On the networker GUI go to Group Control
if there is a group still running check it with the Details option is there a 
client still pending?

if it is not critical you can stop the group there with the stop button (my gui 
is on unix)
