IT04191: THREAD SUSPENSION NOT CORRECTLY ABORTING SERVER IF THREAD IS REPORTED AS BEING NOT ABLE TO BE SUSPENDED

APAR status

• Closed as program error.

Error description

• In 12.10.xC3 and later, default behavior for an asserting thread
  is to check to see if the thread can be suspended, rather then
  abort the server.  However, there are conditions where we can
  not suspend the thread, and if that is the case, the server
  should then abort and be brought off-line.
  
  This is not working, so you see assertions like this where it
  reports the server should abort, but the server does NOT abort.
  
  Example:
  
  18:16:49  Assert Failed: Thread exited with 2 buffers held.
  
  18:16:49  IBM Informix Dynamic Server Version 12.10.FC4X9
  18:16:49   Who: Session(153438, usr@machine, 4458382,
  7000000780fedf8)
          Thread(155189, sqlexec, 7000000852b7e08, 67)
          File: rsshmem.c Line: 2082
  18:16:49   Results: Dynamic Server must abort
  18:16:49  stack trace for pid 2359896 written to
  /backup/IDSdump/af.621d0750
  18:16:49   See Also: /backup/IDSdump/af.621d0750
  18:16:54  Thread ID 155189 will NOT be suspended because
            it is holding a buffer.
  
  But after that sequence of messages, the server is still up, and
  it shouldn't be.
