Symptoms

tmm memory growth over time.

Impact

tmm memory usage can grow over time eventually causing memory exhaustion.

Conditions

Conditions leading to this issue include: one or more virtual servers, NATs, SNATs, or LSNs with more than four VLANS in a vlan allow or vlan deny list.

Workaround

Mitigation: Minimize the number of VLANs in the VLAN list for virtual servers, NATs, SNATs and LSNs. Minimize the number of configurations changes to Self-IPs, virtual servers, NATs, SNATs and LSNs.

Fix Information

Configuration objects with more than four vlans in vlan list no longer causes memory utilization to increase over time.
