DOCUMENT:Q111328 30-JUL-2001 [lanman] TITLE :DosReadMailslot Reads Incorrect Data Under Stress PRODUCT :Microsoft LAN Manager PROD/VER: OPER/SYS: KEYWORDS: ====================================================================== SYMPTOMS ======== An application can fail because DosReadMailslot sometimes returns a message that was not addressed to it. Generally this occurs when mailslot traffic is heavy. CAUSE ===== The code used when writing mailslot data to a local mailslot is not being marked as busy early enough in the routine to keep other mailslot datagrams from affecting the data. RESOLUTION ========== A fix for the LAN Manager MS-DOS redirector corrects this problem and is available as CSD00.079. STATUS ====== Microsoft has confirmed this to be a problem in LAN Manager version 2.2. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available. Additional query words: 2.20 2.2 mailslot ====================================================================== Keywords : ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
