APM - Lease pool not releasing IP address

Hi all,

We currently have APM issuing IP addresses to our VPN users. I've been monitoring the logs during testing and it seems as though when a user is disconnected, the IP address is not released from the lease pool.

Jan  8 13:32:43 slot1/ notice tmm[6646]: 01490607:6: bc616685: IPv4 Cleanup: failed to release IP 10.0.0.46

What would be causing this to happen? I've tried searching everywhere for a solution, but have come up with nothing.

I'd also like to be able to see where these IPs have been assigned. Is there any way to do so via CLI?

Thanks in advance.

    Hi

    it's a known bug.

    ID442656 - Fixed race condition of multiple establishments/teardown of PPP tunnels lead to loss of availability of leasepool addresses.

    solved in later HF for 11.4.0/11.4.1/11.5.1 (check the RNs)

    Which version are you running? I had a workaround (to clean the leasepool) working on 11.3.0 but not working anymore in later versions, due to a change in the TMOS.
