Sql Server can't stop

Today I had a problem with the SQL Server. The SQL Server has crashed and I can't connect to it. When I try to restart the SQL Server it remained in the STOP_Pending state for 30 minutes, then I killed the process.

I have this error message in the error log. I can't find what the error means. Does anyone have any idea?

Thanks
