software freeze

Post by elpacino » Thu Feb 05, 2015 12:33 am

Anyone know how to debug software hangs/freezes?
Anyone know how to debug/diagnose software hangs/freezes down to the "nitty gritty level" level? I mean like going into something like Process Explorer/Monitor and digging through threads and process trees.

Thats exactly where you start...

Fire up procmon, get really good at filtering. But you have to be careful because sometimes you can filter out too much.

Start by filtering to the process and see if it's doing anything while it's hung. Then look at what happened just before it hung. Then take a peek at all processes to see if anything happened just before it hung.

You can also enable debug symbols so you can look at the process stack. Sometimes you can get a clue about what is going on by the function that is being called....

It's almost more of an art than a science!
