SQL Agent Job sometimes failes

We have a SQL Agent Job which runs every day (at night). Sometimes this job failes at one step with the following error message:

"Unspecified error occurred on SQL Server. Connection may have been terminated by the server. [SQLSTATE HY000] (Error 0) " .

At this time nothing is going on on the database!
The step which failes executes an Stored Procedure.
Here is the Code of that Stored Procedure:
DELETE FROM table WHERE DATEDIFF (dd, column, getdate()) = @iAnzahlTage)
SELECT table, table2, var1 = convert(varchar(8), ...)
 
INTO #tmpTable
FROM Table
WHERE DATEDIFF ...
AND ...
 
 
INSERT INTO ...
SELECT ...
FROM #tmpTable
GROUP BY ...
 
drop table #tmpTable

>DELETE FROM table WHERE DATEDIFF (dd, column, getdate()) = @iAnzahlTage)
should be better:
DELETE FROM table WHERE column < DATEADD (dd, - @iAnzahlTage, getdate()) 
same expression should be used on the other WHERE clauses, and ensure you have a index on the column...
