I cannot view my Log Viewer or even purge the Event Log in the Scheduler.

This is the message in the Purge Schedule History:

EXCEPTION: System.Data.SqlClient.SqlException: Timeout expired.  The timeout period elapsed prior to completion of the operation or the server is not responding.
   at System.Data.SqlClient.SqlCommand.ExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream)

   at DotNetNuke.Services.Log.EventLog.DBLoggingProvider.DBLoggingProvider.PurgeLogBuffer()

Ideas anyone?

If you want to clear out the contents of the entire table then "TRUNCATE TABLE EventLog" is much faster as the deletes are not logged on a row by row basis.
