DOCUMENT:Q174468 13-JUN-2001 [sna] TITLE :SLI_SEND Fails To Complete, Causing Win32 SLI App To Hang PRODUCT :Microsoft SNA Server PROD/VER:WINDOWS:3.0,3.0 SP1 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft SNA Server, versions 3.0, 3.0 SP1, on platform(s): - the operating system: Microsoft Windows NT ------------------------------------------------------------------------------- SYMPTOMS ======== A Win32 SLI application may hang waiting for an SLI_SEND to complete. This may occur if the host has sent an UNBIND on the session, which causes the SLI library to issue an RUI_TERM. CAUSE ===== SNA Server's Winsli32.dll does not return the SLI_SEND Post response to the SLI application after an RUI_TERM is sent and this causes the application to hang. RESOLUTION ========== Microsoft has updated Winsli32.dll so that it returns all outstanding SLI verbs to the application when a session fails. STATUS ====== Microsoft has confirmed this to be a problem in SNA Server version 3.0 and 3.0sp1. This problem was corrected in the latest SNA Server version 3.0 U.S. Service Pack.
