[ADSM-L] NDMP error ANR4950E when upgrading EMC Celerra DartOS

Greetings,
        We are running TSM 5.3.4 on AIX 5.3.  We just upgraded one of
our EMC Celerra servers from Dart OS 5.4.15.2 to 5.5.25.2.  Now our NDMP
backup is failing because of a ANR4950E error.  The actlog is shown
below.

It looks as if 100GB of data is backed up, but the error occurs in
recording the TOC data afterward.

The backup has been working successfully for months before the upgrade.
Can anyone give me any insights as to why?  IBM's knowledgebase was no
help at all.  The only reference it had for this error was specific to a
problem on Netapp, not EMC Celerra.  One thing I should note is that we
are doing a differential, and we have not done a full since the upgrade
this weekend.  The full takes 40 hours to complete, so we only do it on
the weekend.
