45F

Explanation
A SYSEVENT QUIESCE macro failed while a SYSEVENT
TRANSWAP or REQSWAP was pending.  A retry was not possible.

System action
The system abnormally ends the address space being
swapped. The system writes messages and a logrec data set error record.

System programmer response
  This is probably a system error.
Resubmit the job.  If the problem recurs, search problem reporting
data bases for a fix for the problem. If no fix exists, contact the IBM® Support Center. Provide the
logrec data set error record and the SYSOUT output for the job.
