Nonpaged bytes increase due to hyperthreading

Just a message to help if anyone is having problems with nonpaged
bytes overflow. We have an application that captures video and
compresses and stores it. The application was running fine until we
recently upgraded to a new computer running supermicro P4SCi. After
the installation the server started to crash every day due to nonpaged
bytes overflow with an event 2019.

We checked all the processes using the perfmon but non of the
processes were increasing the nonpaged bytes. So we concluded that the
leak must be in the kernal.

When I called supermicro their tech support asked me to disable
hyperthreading to see if it had any effect. Well that stopped the
problem. I don't think this problem is unique to this board(P4SCi).
Basically looks like if an application is making hardware level calls
directly hyperthreading is a bad idea.

I just wanted to let everyone know.

Good luck

I'd be interested to see the results of this on Windows Server 2003. 2000 was not written with Hyperthreading support. 2003 was. I wonder if the results would change.
