[Orca-users] Re: Gaps in Orca graphs

[Blair Zajac]

Hi David,

I've run large installations of Orca all writing their data to a NetApp
NFS server and we never saw this problem.

What kinds of jobs do anything to the percol- files?  If they're backups,
then they should just read them, not touch them in any way.
