Error description
Abend0c4 rc11 (rsncode=11) in IRRRIU00 in loadmod
IRRRFR10 occurs in WebSphere application server server region.
 The following messages can also appear in the application
server
 server region:
 ICH409I 0C4-011 ABEND DURING IRRSIU00 PROCESSING.
 ICH409I 0C4-011 ABEND DURING IRRSDU00 PROCESSING.
 followed by an svc dump in csect IRRRDU00 with abend0C4-011.
 This problem can also surface as
 ICH409I 378-010 ABEND DURING IRRSDU00 PROCESSING.
 followed by an svc dump with abend378 rsncode=10 in IRRRDU00
.
ACEE's are being re-used before being freed, resulting in 378
abend.  IRRSIA00 was being invoked with the RACF managed ACEE
option enabled. This caused RACF to distribute the save ACEE to
multiple threads. BPX1TLS is called to affix the ACEE to the
thread. This call frees the USP (USS chunk of the ACEE) and
recreates a new one. The 378 abend is caused by 2 threads
trying to free the same USP.

Customer is running WebSphere Application Server V4.0.1 for
for z/OS and OS/390, and receiving the following abends:
ABENDS04C6/ABEND04C6 and ABENDS378/ABEND378  and this error
message:
BBOU0759E Credential handling function RunAsSetSpecCred failed
in USS callable service BPX1TLS with
Return Value (hex): ffffffff, Return Code (hex): 9d, and
Reason Code (hex): be800fe.

After reviewing the SVCDumps we were able to find that ACEE's
were being re-used before being freed, resulting in 378 abend.
IRRSIA00 was being invoked with the RACF managed ACEE option
enabled. This caused RACF to distribute the save ACEE to
multiple threads. BPX1TLS is called to affix the ACEE to the
thread. This call frees the USP (USS chunk of the ACEE) and
recreates a new one. The 378 abend is caused by 2 threads
trying to free the same USP.
Problem conclusion
There is a mismatch between the RACF INTA_MANAGED SAF option
(managed ACEE's) and how WebSphere 'expected' that option
to behave.  The initACEE option needs to be removed to
avoid having the same ACEE attached to multiple threads.

APAR PQ85832 is associated with SERVICE LEVEL W401611 of
WebSphere Application Server version 4.0.1 for z/OS and OS/390.
