00E50080

Explanation
 An execution unit (SRB or TCB) processor determined
that the current MVS™ Functional
Recovery Routine (FRR) stack contained one or more entries for FRR's
which should not exist. This check is made at the conclusion of a
resource manager function executing under the SRB or TCB.

System action
 An SVC dump is requested specifying an abend
code of X'04E' and this reason code.  The extraneous FRR entries are
deleted from the stack. Execution continues.  The application is not
notified.

Operator response
 Notify the system programmer of the SVC dump.

System programmer response
 If you suspect an error in DB2®, you might need to report the problem. For information about identifying and reporting the
problem, see Collecting diagnostic data.

Problem determination
 MVS console
data is logged and the SVC dump is taken. No record is written to
SYS1.LOGREC.
 One or more resource manager functions created
an FRR which was not deleted. Examine the current FRR stack in the
PSA of the active CPU. The only valid stack entries are those established
by DB2 and MVS Dump Services and, if DSNVEUS2, an entry
established by that module. The format of the FRR stack is provided
as data area FRRS in the appropriate MVS debugging
guides.
