The job was stopped prior to completion by Shutdown Sequence 0.

We got below error during one of the sql server agent job running.

The job was stopped prior to completion by Shutdown Sequence 0. 

We are using SQL Server 2008 R2. I dont see anything in SQL Server error log or agent log showing any service shut down. Both services were up around the time this error came and the job failed.
We started the job again later and it worked.

Has anyone come across this error? What caused it?

Thanks
