At times there are some held threads which prevents DB2 subsystem down for maintenance purpose. We can follow these if we require:

These are some console commands which can be tried:

/MODIFY DSN1IRLM,ABEND,NODUMP

OR
/F DSN1IRLM,ABEND


THEN IF NECESSARY

/C DBM1

/FORCE DBM1 (LAST RESORT)

OR

/C MSTR

/FORCE MSTR (LAST RESORT)
