APAR status
Closed as program error.

Error description
An ABEND S0C4 occurs in BBOCASHS offset OFF68 if the control
region is shutting down while an HTTP SSL session is being
started up. The shutdown logic zeros a pointer to the session
being started which causes data values to be invalidly
referenced from low storage. These data values lead to the SOC4.

A STOP was issued to Server.  The server was under a load
receiving HTTP SSL requests.  The STOP processing deleted the
HTTP SSL Listener Session while it was still being
used/referenced by an inbound accept.  The information extracted
from the deleted Session's storage was passed to bbocashs.plx
which lead to the ABEND0C4.
Problem conclusion
Code has been added to serialize the deletion of the Listener
Session against their use.  The serialization was added to all
protocols.

APAR PQ71794 is associated with SERVICE LEVEL W401503 of
WebSphere Application Server V4.0.1 for z/OS and OS/390.
