I guess I have different questions than I have already seen.  How is the memory 
usage on the node?  Is it 32 or 64 bit?  Is the agent hanging or working during 
the 9000 seconds?
We have 2 systems that back 10M+ objects in an equally crazy number of 
directories and we have not seen the error you have.  1 machine is 32 bit and 
is using memory efficient disk cache and the other one is 64 bit and does not 
needs memory help.  Both have static file systems during the backup. (That is 
another story.)
We have seen a similar error to yours on 2003 servers with SP2.  Take a look at 
Microsoft KB 948496 if the server is running SP2.

failing

I have two separate Windows 2003 boxes both running running  v5.5.1.10
client that are both failing their incrementals every night. Both of these
boxes have hundreds of thousand of files all spread into multiple
directories. In fact, each day, a new directory is created and then
multiple subdirectories are created under it and thousand of files in each
of those subdirectories. The reason I say this is because I don't think it
is a candidate for multiple virtual nodes because of the new directories
that are created every day.

I do have journaling turned on although it doesn't seem to help with the
large number of files either as when I run an incremental manually,it takes
forever and never seems to finish.

I thought about doing image backups of the drive where the thousands of
files live but when I tried it, it backed up about 14g and then just hung
and never continued. I had to cancel it after waiting for an hour or so.


What is my best strategy for dealing with these two boxes that are
generating thousands of new files in new directories every day? The huge
number of objects in the TSM DB are starting to cause quite a few problems
with daily processing also as expiration is running longer and longer since
I think it is choking on the number of objects.

And to make it even weirder, they both fail incrementals at night and the
only error I can find is:

ANR0481W Session 16603 for node <SERVERNAME> (WinNT) terminated
 - client did not respond within 9000 seconds. (SESSION:
 16603)

I'm starting to think that TSM is just not the backup solution for either
of these boxes.
