SYMPTOMS
When processors are utilizing 100 percent CPU and an instance of the Dllhost.exe file begins to consume the processor, clients attempting to access the affected Web site do not receive any error messages in their browser except for the occasional HTTP 500 error. After you obtain a dump file, you may see a stack with the following fault points (if you have the correct symbols loaded): ChildEBP RetAddr Args to Child 02eafde0 04bc2221 7ff805bc 00000001 7ff805b4 KERNEL32!_InterlockedExchange+0xa [..\i386\critsect.asm @ 168] 02eafe28 04bd006e 0fffff00 7ff800b4 ffffff00 mscsups!CPOCacheEntry__Lock+0x5d [d:\cs40\private\cs40\server\iprofile\mscsups\pocache.cpp @ 155] 02eafe40 04bcea3f 02f6b250 0714b988 00000050
