The information in this article applies to:
- Microsoft SNA Server 2.0, when used with:
- the operating system: Microsoft Windows NT
- Microsoft SNA Server 2.1, when used with:
- the operating system: Microsoft Windows NT
- Microsoft SNA Server 2.11, when used with:
- the operating system: Microsoft Windows NT
This article was previously published under Q135355 SYMPTOMS
When a Local APPC LU / Remote APPC LU partnership is defined in the SNA
Server configuration file, SNA Server automatically negotiates the
parallel session limit with the remote system when the connection that
owns the Remote APPC LU is started. This negotiation occurs over an
SNASVCMG mode session between these APPC LUs, using the Change Number
of Sessions (CNOS) command as defined by IBM SNA architecture.
When a large number of APPC LUs are configured in SNA Server and SNA Server
is started, SNA Server builds the SNASVCMG mode BIND messages and CNOS
commands for all these LU/LU/mode partnerships and queues them internally
until they can be processed. If there are so many partnerships that the
internal SNA Server queue becomes exhausted, SNA Server logs the following
event in the Windows NT application event log:
Event 11 (1178) Initialization Failure
1178 = Insufficient resources for automatic session limit negotiation
After this error occurs, the SNA Server service terminates.
CAUSE
SNA Server interprets this condition as a fatal error, causing the SNA
Server service (SNASERVR.EXE) to generate an SNA Server dump file.
RESOLUTION
You can correct this problem by installing an SNA Server 2.11 fix that is
now available. This fix reduces the severity of the error so that SNA
Server attempts to recover from the condition, rather than failing.
Microsoft has updated the file SNASERVR.EXE to correct this problem.
To work around the problem without installing the fix:
STATUS
Microsoft has confirmed this to be a problem in SNA Server for Windows NT.
This problem was corrected in the latest SNA Server for Windows NT, 2.11
U.S. Service Pack. For information on obtaining the Service Pack, query on
