Hi Everyone,

Fairly new to DNN and Need Help... I have a company intranet site in testing phase going to production soon. I have a parent portal site with multiple child portals underneath for various departments. When I went to one of the child portal(#1) Event Viewer I would get the following error message:

Error: Event Viewer is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. ---> 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.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj) at System.Data.SqlClient.SqlCommand.FinishExecuteReader(SqlDataReader ds, RunBehavior runBehavior, String resetOptionsString) at System.Data.SqlClient.SqlCommand.RunExecuteReaderTds(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, Boolean async) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, DbAsyncResult result) at System.Data.SqlClient.SqlCommand.InternalExecuteNonQuery(DbAsyncResult result, String methodName, Boolean sendToPipe) at System.Data.SqlClient.SqlCommand.ExecuteNonQuery() at Microsoft.ApplicationBlocks.Data.SqlHelper.ExecuteNonQuery(SqlConnection connection, CommandType commandType, String commandText, SqlParameter[] commandParameters) at Microsoft.ApplicationBlocks.Data.SqlHelper.ExecuteNonQuery(String connectionString, CommandType commandType, String commandText, SqlParameter[] commandParameters) at Microsoft.ApplicationBlocks.Data.SqlHelper.ExecuteNonQuery(String connectionString, CommandType commandType, String commandText) at Microsoft.ApplicationBlocks.Data.SqlHelper.ExecuteNonQuery(String connectionString, String spName, Object[] parameterValues) at DotNetNuke.Services.Log.EventLog.DBLoggingProvider.Data.SqlDataProvider.PurgeLog() at DotNetNuke.Services.Log.EventLog.DBLoggingProvider.DBLoggingProvider.PurgeLogBuffer() at DotNetNuke.Services.Log.EventLog.LogController.PurgeLogBuffer() at DotNetNuke.Modules.Admin.Log.LogViewer.Page_Load(Object sender, EventArgs e) --- End of inner exception stack trace ---

When I go to another child portal(#2) Event Viewer, I would get the following error message:

Error: Event Viewer is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Attempt to release mutex not owned by caller. (Exception from HRESULT: 0x00000120) ---> System.ApplicationException: Attempt to release mutex not owned by caller. (Exception from HRESULT: 0x00000120) at System.Threading.ReaderWriterLock.ReleaseWriterLockInternal() at DotNetNuke.Services.Log.EventLog.DBLoggingProvider.DBLoggingProvider.PurgeLogBuffer() at DotNetNuke.Services.Log.EventLog.LogController.PurgeLogBuffer() at DotNetNuke.Modules.Admin.Log.LogViewer.Page_Load(Object sender, EventArgs e) --- End of inner exception stack trace ---

Does anyone knows what the cause of this? and any suggestions to resolve this? I am not able to see the events of any portals.

I am running the site under:
-- Windows Web Server 2008
-- MS SQL 2005 
-- DNN v4.08.00

Any help is appreciated

Ken

typically this means the eventlog is so large the scheduled task which is intended to keep it reasonably size times out. You can manually clear the data out, by using a truncate option (as it's not logged it's much faster than a delete operation)

Connect to your sql 2005 machine with the sql server management studio, click on your database, open a sql window and type the following

TRUNCATE TABLE EventLog

This will empty the table, allowing to function correctly (it should also speed your site up as writing eventlog entries to a large table is slower than to a smaller table)
