The information in this article applies to:
- Microsoft Windows NT Server 4.0 Terminal Server Edition
- Microsoft Windows NT Workstation 4.0
- Microsoft Windows NT Server 4.0
This article was previously published under Q178381 SYMPTOMS
Over time, the Windows NT system responsiveness appears sluggish, and
Clients may report a gradual decrease in system performance.
By tracking the amount of Private Bytes for Snmp.exe, it can be observed
that, over time, it increases without decreasing. This is viewable using
Windows NT Performance Monitor by selecting the following counter to
monitor:
Object: Process
Instance: SNMP
Counter: Private Bytes
CAUSE
If SNMP cannot decode an OID from a network packet, SNMP does not free up
the memory, resulting in a memory leak in the Snmp.exe processes. The
impact of this leak will be more evident on a system running on a network
segment that receive lots of SNMP broadcast traffic.
