CA IDMS has many of these abends:
DC001003 TASK:ttttttt PROG:yyyyyyyy STALLED WAITING FOR PROGRAM xxxxxxxx
Release : 19.0
Component : CA IDMS/DB
The error can be caused by insufficient space to load the program either in the program pool or reentrant pool or due to shortages in the storage pool.
It can also be caused by varying the program to new copy with DCMT V PROG NC command while it is still being used by an active task so IDMS has to wait until that task finishes before it can be reloaded. Issue the following command to determine the status of the program:
DCMT D PRO *.xxxxxxxx
Reload the program using the IMMEDIATE operand of the DCMT command:
DCMT D PRO xxxxxxxx NCI
