MSMQ - causing 100% CPU Utilization

I am supporting an application built inhouse (the developer is no longer with the company).   Data is accessed through a web front end, from a 3rd party document storage application.  This is done via MSMQ.  I am seeing that when transacations are queued in MSMQ private queues, the CPU utilization jumps to 100%.  As soon as these transactions are processed, the CPU drops back down to an acceptable level.  Note, in case this is important, we are running Windows 2000 Server.  Any ideas?

Are you already running servicepack 4 for Windows 2000? If not, install it.

I'm running servicepack 4.   I have read some info that indicates I should upgrade to SP 5?
There is no servicepack 5. However, there is a post-sp4 update package.
If you're running into troubles with MSMQ, I would also recommend to update to the latest version of MDAC (2.81):

I hope this helps!
