For a single IP address we see 2 sessions in the system when we do pem_sessiondump --list.
Duplicate sessions creates confusion as to which session is the active one used for an IP.
Create a static subscriber configuration without the IP address and send radius start to create session with 2 IP address. Delete the master IP (first one) and send radius start with same IP.
Make sure radius stop is received for both the IP addresses before sending a new one.
Issues has been fixed now. No more duplicate sessions for the same IP address.
