Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• ABEND46D RC10 is issued when ESPIE processing is scanning the
  chain of ESPIE environments to be deleted and finds at least
  one ESPIE environment that was not created at the same RB level
  as the ESPIE RESET was issued at.

  * PROBLEM DESCRIPTION:                                         *
  * An ABEND46D-10 can occur trying to do                        *
  * an ESPIE RESET (aka delete) to remove                        *
  * the null ESPIE exit that is sometimes                        *
  * established by the EXEC command when                         *
  * a REXX exec is invoked by a caller                           *
  * who already has an ESPIE. The EXEC                           *
  * command ESPIE can only be reset when                         *
  * done at the same RB level as where it                        *
  * had been established. Issuing the                            *
  * ESPIE RESET from a later RB will                             *
  * result in an ABEND46D.                                       *

  ABEND46D RC10 is issued when ESPIE processing is scanning the
  chain of ESPIE environments to be deleted and finds at least
  one ESPIE environment that was not created at the same RB
  level as the ESPIE RESET was issued at.
  .
  This problem can be seen if a REXX exec invoked by the EXEC
  command is hit by a non-retryable abend that causes the REXX
  recovery and EXEC command recovery to percolate. The EXEC
  command's recovery will attempt to remove any null ESPIE it
  had established when its recovery is unable to retry back into
  the mainline EXEC code (under the original RB) to remove the
  ESPIE.  However, while running in the EXEC command recovery it
  is running under the abend SVRB, which is a lower level RB
  than the RB under which the ESPIE had been established. This
  results in the ABEND46D RC10.
  .
  This problem cannot occur if the REXX exec or EXEC command
  processor is hit with a retryable abend, or if the EXEC
  command does not see any abend, nor can it occur if the caller
  of the EXEC cmd did not already have its own ESPIE established
  when it invoked EXEC.
  

Problem conclusion

• The EXEC command will verify that it is at the correct RB
  level when doing an ESPIE RESET to remove an ESPIE that it had
  previously established.
  
  If EXEC is not running at the correct RB level, as would be
  the case when the code to reset the ESPIE gets control under
  the EXEC command's ESTAE, then EXEC will avoid doing an ESPIE
  RESET. In this case, the ESPIE will be automatically reset
  by MVS when the RB terminates under which the ESPIE had been
  established. That is, when the EXEC command's RB terminates,
  MVS will automatically terminate any remaining ESPIE that had
  been previously established by that RB.
