SYMPTOMS
========
If a Win32 SNA Server application opens multiple logical unit (LU) sessions at
the same time by calling SLI_OPEN, some SLI_OPEN requests may stop responding
(hang) and never complete. SNA Application LUA API tracing shows that the
underlying RUI_INIT is completed for every SLI_OPEN that was issued, but one or
more SLI_OPEN requests may fail to complete.
CAUSE
=====
A timing window within the Winsli32.dll code can result in SLI_OPEN hanging if
the RUI_INIT callback happens before the verb returns control.
RESOLUTION
==========
To resolve this problem, obtain the latest service pack for SNA Server 4.0. For
additional information, please see the following article in the Microsoft
Knowledge Base:
Q215838 How to Obtain the Latest SNA Server Version 4.0 Service Pack
WORKAROUND
==========
Reduce the number of SLI_OPEN requests that are issued at the same time, or
serialize all SLI_OPEN requests.
STATUS
======
Microsoft has confirmed this to be a problem in Microsoft SNA Server versions
4.0, 4.0 SP1, 4.0 SP2, and 4.0 SP3.
This problem was first corrected in SNA Server 4.0 Service Pack 4.
