Problem IT04191 Status: Closed

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

product:
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10
Problem 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.
