The TDP backup is failing on a server that I recently loaded AIX 5.1 64-bit
on.
The backint/TDP version is 3.2.0.13, TSM client is 5.1.5.0.
The TSM server log shows error:

ANR0480W: The session is ended because the communications link has been
closed by a network error or by the client program.
The communications time out in the dsmserv.opt is 3000 seconds.

netstat -in does not show any errors on the interfaces

The TSM client dsmerror.log shows psMutexLock deadlock condition

The SAP brbackup log shows:
BR266E, Program ....backint ......  interrupted, exit status: b000b
BR272E, Execution of program ....backint..... through pipe failed
BR231E, Backup utility call failed

Thanks for your help.
