Error description

• You are running CICS TS 3.2 and receive the following
  message:
  DFHSM0133 CICS is under stress (short on storage above 16MB)
  A dump at the time of the SOS condition showed the largest
  DSA was the ECDSA.  Within the ECDSA the largest subpool
  was BAGENRAL.
  There is an Omegamon task suspended for BAGENRAL storage.
  It has issued an EXEC CICS INQUIRE-ACTIVITYID command.
  The CICS internal trace shows this task has also issued
  the following commands:
  STARTBROWSE-ACTIVITY
  GETNEXT-ACTIVITY
  STARTBROWSE-EVENT
  GETNEXT-EVENT
  It turns out some storage - BABUSEG1 getmained from the
  BAGENRAL subpool during STARTBROWSE-EVENT processing
  is not getting released properly.

  CICS BTS is in use, and the BTS repository contains a large
  number of activities in COMPLETE ABENDED state. An application
  has been browsing the abended activities and associated events,
  via the STARTBROWSE-EVENT SPI. During these browses, CICS has
  experienced a Short on Storage condition in ECDSA. The storage
  appears to have been consumed by storage subpool BAGENRAL.

Problem conclusion

• DFHBAAC has been amended so that storage for BABUSEG1 (in the
  BAGENRAL subpool) is released immediately after having been
  GETMAINed, if it is found that there is no event pool associated
  with the activity.
