 The SSL server is seen to shutdown unexpectedly, after
 reporting these error messages:

 ****************************************************************
 For a secure connection, when GSK_ERR_CONNECTION_CLOSED has been
 received by the SSL server 'write' handler, after all data has
 been written to a socket, the SSL server may abend with these
 error messages reported:
 
   ...
   DTCSSL107W Internal error: fd 12 ssl send 987 bytes: SSL
   session closed by remote, dropping data
   DTCSSL107W Internal error: fd 12 ssl send 943 bytes: SSL
   session closed by remote, dropping data
   Assertion failed: FD_ISSET(scb->fd_group en_listen .fd,
   &fset en_read .fd) || FD_ISSET(scb->fd_group en_listen .fd,
   &fset en_write .fd) || FD_ISSET(scb->fd_group en_relay .fd,
   &fset en_read .fd) || FD_ISSET(scb->fd_group en_relay .fd,
   &fset en_write .fd), file: SSLDSPTC C A1, line: 438
   ...
   CEE5207E The signal SIGABRT was received.
   ...
 
 PROBLEM CONCLUSION:
 In part SSLDPUMP C, the SSL write handler has been updated in
 order to better handle the return code
 GSK_ERR_CONNECTION_CLOSED.  The revised code will now force a
 close of a secure session when there is no read or write event
 that needs to be handled.  Parts SSLDSPTC H and SSLDSPTC C also
 are updated to support the new code in SSLDPUMP C.
