Another tool for your tool belt from SysInternals Mark Russinovich. Why would you need this in SharePoint land? Ever had a process spike and you would have liked to capture a memory dump for analysis and you just happened to miss the occurrence of the event? I have, and I know that a few other have as well. There are a few work arounds that can be done with some other tools out there.

“ProcDump is a command-line utility whose primary purpose is monitoring an application for CPU spikes and generating crash dumps during a spike that an administrator or developer can use to determine the cause of the spike. ProcDump also includes hung window monitoring (using the same definition of a window hang that Windows and Task Manager use) and unhandled exception monitoring. It also can serve as a general process dump utility that you can embed in other scripts.”
