Help with Scusi Tracer app Backup exec 2010

[learning]

I have a world of problems with the backups at the moment, rather than bore you all though... can anyone tell me , when running Tracer.exe whilst a backup job is running (at 1/3 of usual speed) , I'm seeing lots of dropped events ie:

------------------------------------------------------------------------------------------------------------------------------------------------------------------

Is perhaps an indication of a problem with our MSL6000 tape lib , or is this a usual thing to see if you run the tracer during backups?

I can't find any help on the net anywhere...

Thanks

Could you post the error message or the issue that you are facing during backups.
