ATB80036I Buffer storage not available for Receive processing.

Detecting Module:

Explanation
 A TP called an APPC/MVS conversation service.
APPC/MVS could not obtain enough storage to store data to be sent
or received in the conversation. This might be an intermittent error.

System action
 The system returns a product_specific_error (decimal
20) return code to the caller of the conversation service.

System programmer response
 Ensure that the amount of buffer
storage specified on the BUFSTOR parameter in the start procedure
for APPC/MVS (ATBINITM in SYS1.PROCLIB) is large enough to handle
the data to be transmitted, and that the CONVBUFF parameter specifies
a percentage of buffer storage that is large enough to handle the
sending and receiving of data for the conversation. If you accepted
the default value for BUFSTOR (which is approximately one third of
free auxiliary storage) when you started APPC, ensure that the system
has enough auxiliary storage to handle APPC processing. For more information
about how to control the buffer storage limit, see z/OS MVS Planning: APPC/MVS Management. If
the problem persists, contact the IBM Support Center.

Programmer response
 Try to run the application again.  If the
error persists, contact the system programmer.
