Q: 

asp.net high cpu when traversal HttpRuntime.Cache (.net 3.5)

I'm encountering a high CPU issue that when do this job:

foreach(var c in System.Runtime.Cache) ...

from windbg I can see:

0:043> !clrstack OS Thread Id: 0x2d9c (43) * WARNING: Unable to verify checksum for System.Web.Mvc.ni.dll Child-SP RetAddr Call Site 000000000b83e110 00000642bcffe63b System.Web.Caching.CacheSingle.CreateEnumerator() 000000000b83e1c0 00000642bcffcf91 System.Web.Caching.CacheMultiple.CreateEnumerator() 000000000b83e210 0000064281adc7be System.Web.Caching.Cache.GetEnumerator()

I can't drop this line from project, so can I have a another way to approach my job and avoid high CPU issue?

Thanks for any tips.
