BUG #: 53507 (SQLBUG_70)
SYMPTOMS
Under narrow, but unpredictable timing conditions, SQL Server may experience a divide by zero exception which causes the Sqlservr.exe process to stop. No new connections can be made, and current connections are unable to respond. The errorlog will contain a stack trace that contains this error:
This problem is more likely to occur when running SQL Server Profiler, but a study of the underlying failure mechanism indicates that it can theoretically happen when running other queries.
CAUSE
The problem is caused by a race condition when initializing a local variable, so the exact circumstances cannot be predicted.
WORKAROUND
Before attaching SQL Server Profiler, run this query from any client session:
set statistics time on
select 1
set statistics time off
