37B

Explanation
While the system was processing a PURGEDQ macro,
an error occurred in a resource manager termination routine (RMTR).

System action
The system records the address of the failing
service request block (SRB) in a logrec data set error record. The
system asks for a retry and PURGEDQ processing continues. The system
does not return control to the RMTR in which the error occurred.

System programmer response
  Do the following: Use the program status word (PSW) address in the logrec data set
error record to identify the failing RMTR.
Search problem reporting data bases for a fix for the problem.
If no fix exists, contact the component group associated with this
module at the IBM® Support Center.
Provide the logrec data set error record.
