cpu-hogging

I'm having a problem with an IIS application that occasionally spikes up in CPU usage, and am trying to use procdump to get a memory dump for examination. I'm running "procdump.exe -64 -mA 9999" where 9999 is the pid of the process. But every time I do it, I get an error:

Only part of a ReadProcessMemory or WriteProcessMemory request was completed.

Doing this also recycles the apppool, relieving the CPU spike, so I can't keep trying until I get it right.

Does anyone know what is going wrong?
