Thanks.  That appears to be it exactly.

Can one revert from 5.2.3.4 to 5.2.3.3 without restoring the tsm db?

Likely suspect: IC43445:

ABSTRACT:
TSM SERVER ABENDS WITH ANR7837S INTERNAL ERROR LOCKCYCLE02
DETECTED

ERROR DESCRIPTION:
 The TSM Server can crash with a LOCKCYCLE02 assertion
 failure. The assertion failure occurs as a result of a
 lock request being aborted which would occur
 from the resource monitor. The crash will only occur if
 more than 1 resource was waiting on a particular
 lock and 2 of those resources have been aborted due
 to resourcetimeout.

 Customer/L2 Diagnostics:
 The traceback for this problem will be the following:
 pkAbort
 pkLogicAbort
 CheckLockCycles
 TmFindDeadlock
 TmDeadlockDetector
 StartThread

 The dsmserv.err will report the following error messages:

 ANR7838S Server operation terminated.
 ANR7837S Internal error LOCKCYCLE02 detected.

 In the activity log just prior to the crash, you will
 most likely see at least 2 occurrances of the following
 message:

 ANR0538I A resource waiter has been aborted.

 Platforms affected: All 5.2.3.4 ITSM Servers

 Initial Impact: High
 Additional Keywords: Assert resource wait admres deadlock
                      locking lockholder core dump logicabort
                      MSGANR7837S
 LOCAL FIX:
 1) Back-level the TSM Server to 5.2.3.3 or prior
 2) Increasing the resourcetimeout may or may not provide
    relief depending on how long the resources have to wait.
