The Microsoft Exchange Information Store service may unexpectedly quit on an Exchange 2000 computer

The Microsoft Exchange Information Store service (Store.exe) may unexpectedly quit. You do not receive an error message, no events or log entries are recorded, and you do not receive any other indicator of a problem.

This problem occurs when a stack overflow occurs on your Microsoft Exchange 2000 Server computer.

A stack is the memory space that each thread of a process uses to operate. A stack overflow occurs when a routine overwrites a part of the stack memory address that the routine does not allocate or own. This situation then causes problems for other routines. If the stack becomes large, insufficient memory may be reserved, and the operating system is therefore not able to handle these stack overflows correctly. The stack overflow that triggers the symptom that is described in this article may be caused by a third-party program.
