NETSTAT Causes Memory Leak

• Microsoft Windows NT Workstation version 4.0

If you have a large number of network connections and run Netstat.exe with the –N and –1 parameters, Task Manager shows memory usage has increased significantly.

NOTE: You do not have to use these parameters for the memory leak to occur.

CAUSE

This problem occurs because NETSTAT fails to free some memory allocations.
