When there is something “unexpected”, SQL Server kills the SPID and generates a dump. There are situations where SQL threads are not yielding (“Non-yielding Scheduler”, “Non-yielding IOCP Listener” or “Non-yielding Resource Monitor”) and there would be data needed to diagnose the problem later, so a dump is generated. 8 нояб. 2017 г.
