1) Increase the number of copies in the host properties of the Master server.
2) Have diffrent volume pool for both the profiles
3) Have diffrent off_site_volume groupfor bot the profiles.
4) Try to avoid overlapping of these vault profiles.
I use a simple way to fix this. Set a Vault Job to run last day on month, select all clients, select policies, all schedules, all m.servers and all retentions. Do a duplicated 2 days ago, and use master server like read and write (no advance option), do the catalog, do the eject and reports.
