APAR status
Closed as program error.

Error description
If a server is not configured for SSL, the control region still
listens for SSL requests on threads started at initialization
time, CR_SSLHSInWorkRoutine.  If an SSL request is received but
SGSKLOAD is not in STEPLIB for the server or in LNKLST, the
control region will abend because of the failure to find DLL
GSKSSL.  The following message will be seen in the control
region job output:
CEE3501S The module GSKSSL was not found.
  From entry point secure_socket_init(SessionHandle*)
This apar is to prevent an inadvertant SSL request from being
handled by the control region when SSL is not configured for
the server.

authorize it.

****************************************************************
A Listener Session is established on the IIOP SSL Port even
though SSL is not available.  If a request is made to the IIOP
SSL port then an attempt is made to initialize an SSL Socket.
Since SSL is not available, this attempt fails with
ABEND0C4/ABENDS0C4. As a result of the ABEND the Control Region
is terminated.
Problem conclusion
Code has been modified in Communications Session Manager
(bbocsmgr.cpp) to start an IIOP SSL Listener only if SSL is
available.

APAR PQ71372 is associated with SERVICE LEVEL W401502 of
