SYMPTOMS
A program that ran under OS/2 version 1.3 stops responding and has to be stopped by pressing CTRL+C. At that point, Os2srv.exe may trap with a Dr. Watson error message that contains:

OS2SRV.EXE

Access violation (0xc0000005), Address 0x01dec73c



CAUSE
Under OS/2 version 1.3, a parent program starts a child session by calling DosStartSession and providing a Queue name in the startdata.TERMQ element. The parent program then waits on the child session by a call to DosReadQueue(Queue name). When the child session terminates, the system sends a message to this queue that makes the call to DosReadQueue return, with the session number of the child session that terminated. Under OS2SS, the end of a session is not signaled in the queue, or DosReadQueue does not return when this is signaled in the queue.



STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.51. This problem was corrected in the latest Windows NT 3.51 U.S. Service Pack. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
