Hi All,

I have a Win2k SP4 server and I think there is a memory leak that causing problems on the server. In the event viewer, I have Event ID 2020: The server was unable to allocate from the system paged pool because the pool was empty.

When I restart the server, it runs smoothly for about 2 days and then I started getting the same errors.

So, here is my questions:
1) how do I figure out if I do have a memory leak? Is there a utility that can run to see if there is a memory leak?

2) if there is a memory leak, is there a way in which I can reset the memeory without having to restart the server?

Any advise would be greatly appreciated.

Thanks.

Hi

This is taken from Windows 2000 Performance Runing and Optimization by Gardinier and Amaris.

Use the System Monitor to watch every counter in the Memory object - particularly Pool Nonpaged Allocs, Pool Nonpaged Bytes, Pool Paged Allocs, Pool Paged Bytes, System Code Total Bytes and System Driver Total Bytes. If a memory leak exists one or more of these counters will continually rise because memory is not being returned.

Also monitor these: Objects:Threads and Objects:Sections - threads is No of active threads, and Section is an area of virtual memory. Both will increase if there is a leak.

This process will help you identify the presence of a memory leak.

Thanks. We were able to determine that there was a problem with the paged pool. There was a MS hotfix available. Since it has been installed, the server has been stable.
