• Closed as unreproducible.

Error description

• The CHIN was canceled while it was in termination
  processing resulting in a S222 abend.
  The S222 abend hit when CSQVDISC was in the process of
  invoking CSQSDSTK to deallocate stack storage.
  CSQVDISC's recovery routine was therefore invoked for
  the S222 abend. However, it did not set up base
  register R12, which resulted in the S0C4 seen here.

  ****************************************************************
  When processing the disconnect of an application address
  space, ABENDs are handled by the Functional Recovery Routine.
  
  While handling an abend (such as an S222 ABEND for a cancel)
  the CSQVDISC function does not correctly establish its base
  registers and may therefore result an S0C4 abend during
  functional recovery, preventing the correct operation of
  the recovery routine.
  

Problem conclusion

Temporary fix

Comments

• Processing has been amended to ensure that all necessary base
  registers have been established before executing the functional
  recovery routine.
