Debug Memory Leak in Printer Driver

NTDEV
1

I have created a printer driver for image manipulation and have noticed
memory usage for spoolsv is not being freed up when printing through my
driver. What recommendations do you have to observe or track memory leaks?
Thanks in advance and all help is appreciated.

Thanks,
Keith

I’ve used pageheap.exe very successfully in the past
(http://support.microsoft.com/kb/286470).

Haven’t needed or used it for a couple of years though. I remember it
was a little confusing to set up, but worked great once I figured it
out.

Also, looking at task manager values for memory used isn’t necessarily
an indication of a memory leak in your driver.
