[Opensim-users] Possible to configure how often sim diagnostics are done?

[Justin Clark-Casey]

That's very odd because the output of "show stats" is extremely similar to diagnostics.  Diagnostics does log some extra 
information, but nothing which should cause this kind of issue.

To be honest, this should be configurable but I am really strapped for time right now.  It would be very handy if you 
could try disabling this manually by commenting out the lines (80-81)

             m_periodicDiagnosticsTimer.Elapsed += new ElapsedEventHandler(LogDiagnostics);
             m_periodicDiagnosticsTimer.Enabled = true;

in the BaseOpenSimServer() constructor in BaseOpenSimServer.cs and see if that makes a difference.

Could this possibly be some issue with writing anything to console?  Do you have logging settings which would otherwise 
write data?
