This means that JunOS would have spun off the disk but didn't due to a 
bug.  So it's more than just disk monitoring.

This may have impact on the lifetime of the routing engine, but which 
way is not very clear to me (spinning up and down the disk constantly 
when syslog is written versus just keeping the disk spinning).

Personally I don't think this is a big issue one way or the other but 
if you're only writing very little syslog, the "savings" of spinning 
down the disk might be bigger than with us.
