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:

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.
