I find the following information from SQL log:
Error 802: [Microsoft] [ODBC SQL Server Driver] [SQL Server] There is insufficient memory available in the buffer pool.
[Microsoft][ODBC SQL Server Driver] [SQL Server] Check terminated. A failure was detected while collecting facts. Possibly tempdb out of spce or a system table is inconsistent.
Do you all experiencing this and how you all solve it without restart/stopping the SQL server?
