Error message 2
SQL Server Assertion: File: <"logmgr.cpp">, line=5565 Failed Assertion = '!(minLSN.m_fSeqNo < lfcb->lfcb_fSeqNo)'. This error may be timing-related. If the error persists after rerunning the statement, use DBCC CHECKDB to check the database for structural integrity, or restart the server to ensure in-memory data structures are not corrupted.
Process 30:0:0 (0x1dbc) Worker 0x00000000071561C0 appears to be non-yielding on Scheduler 4. Thread creation time: <time>. Approx Thread CPU Used: kernel 0 ms, user 0 ms. Process Utilization 1%. System Idle 95%. Interval: 75000 ms.
This problem occurs because a SQL Server assertion occurs under a spinlock when you restart the SQL Server service.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
A spinlock is a lock where the thread waits in a loop (Spin) that repeatedly checks until the lock becomes available. When the thread remains active but does not perform a useful task, such a lock is a kind of busy waiting. When SQL Server uses a spinlock, the spinlock is typically held until it is explicitly released.
