My w3wp's are recycling every 60 seconds after using too much virtual memory.

I ran the IIS Debug Diagnostic Tool to capture a memory dump before the worker process recycled; the most interesting part seems to be this:

Virtual Allocation Summary

Reserved memory 4.88 GBytes  
Committed memory 328.27 MBytes  
Mapped memory 17.36 MBytes  
Reserved block count   524 blocks  
Committed block count   1082 blocks  
Mapped block count   43 blocks

So that 4.88 GBytes of reserved memory seems really big. But neither the DotNetMemoryAnalysis or the regular Memory Pressure Analyzer seems to tell me where that 4.88 GB went.

How can I find out?
