SYMPTOMS
The information store stops unexpectedly during a service shutdown. If a Drwtsn32.log file is produced, you may see an entry similar to the following:

*> State Dump for Thread Id 0x2f8 <*

eax=ffffffff ebx=77e836e6 ecx=00000384 edx=ffffffff esi=61bd3014 edi=77e836d5 eip=77e836f0 esp=191eff74 ebp=191effb4 iopl=0        nv up ei pl nz na po nc cs=001b  ss=0023  ds=0023  es=0023  fs=0038  gs=0000             efl=00000206

CAUSE
A region of virtual memory that is used for performance monitor data is freed before the store task threads have ended. When the store task threads try to decrement a performance monitor counter in this region of virtual memory, a failure occurs.

This condition is rarely seen because the thread that controls the virtual memory region usually waits long enough for all the task threads to shut down before they release the memory section.
