Help: Error Log

Dear all,
After I checked the SQL Server Log i found error like this:
1. Error: 17883, Severity: 1, State: 0
What does it mean?
2. Login failed for user 'sa'.
Almost every minute this error occured.
Does someone know what's happening to my SQL Server?
Thanks
Robert LieRobert,
1. This message means your scheduler appears to be hung. See the following
for more info:
New concurrency and scheduling diagnostics added to SQL Server
http://support.microsoft.com/kb/319892/
2. This means something is trying to login to SQL Server (and failing). Run
SQL Profiler to see what this is. Whatever it is, it shouldn't be using the
sa account.
Mark.
