2421468 - Dual stack system Upgrade/Update - SUM hangs at GETSYNC* or SETSYNC* phase

Symptom

During update/upgrade of Dual stack system , SUM gets into hang situation in a GETSYNC* or SETSYNC* phase.

Examples of phases where this can occur:

MAIN_SHDIMP/SETSYNC_SHD_FINISHED
MAIN_PROFSTART/SETSYNC_PROFILES_CHANGED
MAIN_SHDPREPUT/SETSYNC_SHD_STARTED_PRE 
MAIN_SHDCRE/SETSYNC_EULCK_START_D1
MAIN_SHDIMP/GETSYNC_PREUP_FINI_D
MAIN_PROFEND/GETSYNC_MODPROF_STARTED 
..etc.


When this occurs, there is no update in logs and no activity being performed. Checking the logs in ABAP tab of SUM you can see below info and in JAVA tab of SUM "Waiting for SUM ABAP event"

 In \SUM\abap\log\SAPup.log

----------------------------------------------------------

CURRENTPHASE MAIN_SHDIMP/SETSYNC_PREUP_FINI_D
...started at 201x0119101504# Setting syncpoint PREUPTIME=FINISHED...finished at 201x0119101505 with status SUCCEEDED.
