Symptoms

TMM cores in Network Access scenario when no leasepool is created on the BIG-IP system and IP address assignment is done through the Variable Assign agent (mcget {session.ldap.last.attr.vpnClientIp}).

Impact

Traffic disrupted while tmm restarts.

Conditions

APM network access and no leasepool is created on the BIG-IP system.

Workaround

To work around the problem, create a leasepool on the BIG-IP system; it does not need to be attached to an access policy.

Fix Information
