SNMP Agent Leaks Memory When Queried

ID: Q196270

The information in this article applies to:

Microsoft Windows NT Workstation version 4.0
Microsoft Windows NT Server version 4.0
Microsoft Windows NT Server, Enterprise Edition version 4.0
Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS

Severe memory leakage occurs when the SNMP agent is under stress.

Also, in Perfmon, for the Network Interface Object, you may notice a random number for the first instance, instead of 1.

CAUSE

This problem occurs because, while processing messages, a buffer was used that was never freed.
A regression in Service Pack 4 caused the network interface problem.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update. For information on obtaining the latest service pack, please go to:
