Girish,

I already changed this parameter.  I did not put in a higher value but a lower 
value (30 seconds) as I believed it was because of the fact that the Media 
Server did not cleaned up the staging disk fast enough so that the disk becomes 
full and the Media Server for Disk was set offline.  The upper threshold is 
apparently hardcoded to 98% for Basic Disk (which is, in my mind, ridiculous) 
so it has very little time to start cleaning up when backups are coming in at a 
rate of almost 100 MB/sec).  But this did not solve the issue.  We are 
suspecting something else right now.

Best Regards,
