DOCUMENT:Q142621 08-AUG-2001 [winnt] TITLE :OS/2 Application Does Not Return DosReadQueue Properly PRODUCT :Microsoft Windows NT PROD/VER:winnt:3.51 OPER/SYS: KEYWORDS:kbother ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation version 3.51 - Microsoft Windows NT Server version 3.51 ------------------------------------------------------------------------------- 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.
