I see that out of memory is a fairly common problem, and I'm seeing it now. I'm willing to work with support to provide memory dump, etc.
I'm on win7, 64bit, 8 GB memory. Resharper 6.1 trial version. Visual Studio 2010. About 30 projects, about 200K lines of code.
When I enable resharper it churns at 30-60% cpu until it reach about 2.5GB private working set and then dies. During this time I'm not doing anything in VS, just watching task manager with a sense of doom. <s>
Just let me know what you need.
