APAR Error Description / Circumvention
-------------------------------------------------
A request was made to obtain an advisory lock on bytes within a
stream file. The lock could not be obtained immediately because
another job had the same bytes locked. This other job had
already created a deadlock situation with other byte lock
requests. The system failed with SRC B6005121. When many jobs
were in this situation, the system failed with SRC B6000105. LIC
log entries VL02000606 (the invocation work area is full) were
logged prior to system termination.
CORRECTION FOR APAR 'MA41364' :
-------------------------------
If an advisory lock on bytes in a stream file cannot be obtained
immediately because of a lock conflict, then processing is
performed by the system to determine if a deadlock situation
exists. The function that performs this processing encountered
an unexpected combination of locking data that resulted in a
recursive function looping without end. This PTF prevents the
recursive function from looping without end.
CIRCUMVENTION FOR APAR 'MA41364' :
----------------------------------
None.

None.
Special Instructions
