SYMPTOMS
The SNA Server service (Snaservr.exe) may experience an Access Violation (AV) in the S1ppiusn or S1ppstad function when an application such as Performance Monitor (PerfMon) is querying the SNA Server performance monitor counters. Other applications may also query performance monitor counters, including Compaq's Insight Manager.
If Drwtsn32.exe is configured as the default debugger on the SNA Server/Host Integration Server (HIS) 2000 system, information similar to the following may be appended to the Drwtsn32.log:

CAUSE
A problem in the SNA Server performance monitoring functions can cause invalid output to be returned to the performance monitoring application (for example, PerfMon) or to the Access Violations described here. This problem occurs only under certain conditions, and therefore the problem may occur only rarely and may be difficult to reproduce.
