My printer is sharp and it displayed on the screen fuser temp?

Memory leak in spoolsv.exe I have a Windows 2003 Std sp2 server that is my primary print server for my entire company. We have 40+ different printers configured on it.

About 2 months ago, we started having performance issues with the box... the Print Spoooler service apparently has a memory leak and eventually consumes so much memory that the service stops responding. Print jobs accumulate in the queues but never get printed. As soon as we restart the spooler service, the jobs spit right out.

I've changed all of my printer ports to Standard TCP/IP ports per a suggestion I found on google, and installed SP2 per M$ suggestion, but nothing has helped. spoolsv.exe will go from 2MB to almost 500MB of memory in less than 12 hours.

I can use perfmon to monitor the memory usage and such, but so far I haven't found any utility that will identifiy EXACTLY what is causing the spooler service to leak memory like this. There are so many different drivers that use spoolsv.exe, how can I tell which one is the culprit?
