PoolPage Memory Leak

I have identified one of my servers as having a memory leak in the Page Pool area of system memory. I have correlated that leak with the Services.exe system process. Does anyone know exactly how I might be able to pinpoint the culprit thread that’s causing this leak? By the way, I’ve used Perfmon to monitor its threads but all seem normal. Rather, I’m wondering if there is a way to monitor the Browser, Messenger, Server, and Workstation services, since they all fall under Services.exe. I’m alsoopen to other suggestions. This might help: the problem only occurs when the server is backed up from a remote machine using Veritas Backup Exec. Thanks much.
