When Direct Server Return (DSR) or asymmetric routing with a tunnel is deployed, the TMM process may crash if the 'cmp-hash' setting of a VLAN is set to a non-default value.
The TMM process crashes and traffic disrupted.
There are two scenarios that may lead to this issue: Scenario 1: DSR - DSR is deployed. - The 'cmp-hash' setting of a VLAN is set to a non-default value. Scenario 2: Asymmetric routing - The sys db variable connection.vlankeyed is set to 'disable'. - A VLAN and a tunnel are used to handle asymmetric routing. - The 'cmp-hash' setting of a VLAN is set to a non-default value.
Keep the 'cmp-hash' setting of a VLAN to the default value.
