SNA Client APPC and RUI/SLI Applications May Seem Slow

ID: Q191395

The information in this article applies to:

Microsoft SNA Server, versions 3.0 SP3, 4.0, 4.0 SP1

SYMPTOMS

Under some circumstances, an APPC or RUI application running on an SNA Server Windows NT client may appear to return data slowly. Data meant for the client is returned in normal fashion, but the SNA client's DMOD (part of the client server interface) is not sending this data to the application in a timely manner.

NOTE: This does not occur with the SNA Server client for Windows NT versions prior to SNA Server 3.0 SP3.

CAUSE

A rampipe thread semaphore was being overwritten when multiple initializations of the DMOD through RUI and APPC were made.
