We are experiencing the backup failed 402 error condition nightly on at
least 1 of our Exchange Servers.  We are running:

        The latest TDP for Exchange
        Exchange 5.5 SP4
        NT 4 60a

TSM Server
        AIX 4.3.3 ML10
        TSM 4.2.2.12
        Gigabit

The NT hardware is Gigabit ethernet, ESS Disk with the latest SDD driver,
Magstar Tape.
LAN Backup.

The 402 error condition is related to file handle or other memory resource
shortages in Exchange or NT.  Essentially, until we reboot the box or cycle
the Exchange service the problem is around and no backups will run.  The
funny piece is it can back up the directory but not the information stores.


Level 2 has made us aware of the potential Microsoft fixes but we have them
all in place.  We are out of ideas and desperately seeking any suggestions.
We have theorized that the SDD driver has a leak or the ESS disk is so fast
it overloads the internal buffer and file handles in Exchange.

Has anyone else seen a similar situation after making all the suggested
changes?  If so, have you fixed it and how?
