how to detect where a memory leak is in my application

Question

I have a webpart that loops through web apps, sites, and webs. I using the DoesUserHavePermissions() to check whether or not the user has access to the site. I'm getting an error on this line. I've made sure to dispose of any SPWebs, and SPSites.

Is there a tool that I can use to check where the memory leak is happening?

Thanks,

If you leak SPRequests (SPSite/SPWeb) in a Web Part then it'll listed in the ULS log (Use ULSviewer) to see that.

You can get more information about where the leak occured by setting CollectSPRequestAllocationCallStacks of the ContentService to true see SPRequest allocation callstack logging in SharePoint 2010 and WSS 4.0
