After termination of a Plesk Domain or a Plesk Client subscription IP Addresses that belonged to them are not released and are still marked as leased in corresponding IP pools:
Top > Service Director > IP Manager > IP Pools > %IPs for Plesk Domain and Client Hosting% > Leases
IP Address Occupied By Last Assigned Trial 220.127.116.11 #Cl_ID %plesk_domain% 22-Feb-2012 NO 18.104.22.168 #Dm_ID %plesk_client% 26-May-2011 NO
Click on a Domain or Client ID results in Application error.
The issue can happen if the Plesk Node that hosted Plesk domain or Plesk client in question was switched off during their subscription termination.
Since the issue requires complex manipulations with the database, it is recommended to contact Odin Technical Support for assistance.
