Last time there was deadlock while executing a job on my SQL Server.
The instance hung for a long time and did not respond in time.
Found in Windows Task Manager that one of the SQL process is occupying much RAM and killed the process so that I could restart SSMS and rerun the job again.
However, when tried to login as user 'sa' I get the below error.
'Network related or instance specific error occurred while establishing a connection to SQL server.'
Got the same error when tried to login using 'Windows Authentication' mode.
Can someone please help me with this. I have many jobs on the server and installing a new instance may loose all.
Thank You.
