5: XCPIPE_FREEMAIN_ERROR
Explanation
An attempt to FREEMAIN pipe storage has resulted in an MVS FREEMAIN error.
System Action
The return code from the FREEMAIN is returned in the EXCI subreason field-1. However, the external CICS® interface continues processing the Deallocate_Pipe request. If the request fails with another error, this reason code is overwritten.
User Response
If the problem persists, take a memory dump of the client application program address space, and use the memory dump, with the return code from the MVS FREEMAIN to determine why the FREEMAIN is failing.
