The following e-mail message is sent regularly from the OBAS node :
The licenses of your Parallels Key Administrator price list has been changed. Please check that the unsupported licenses are included in your hosting plans. Please remove the unsupported license deals from your hosting plans.
Some old versions of hosting plans use obsolete KA features.
Please consider deleting unused hosting plans versions from time to time,
this can be done under
Top > Billing Director > Product Manager > Hosting Plans > [HP NAME] > Old Versions tab.
That will also improve general OBAS performance.
