Opened: Jun 23, 2020 Severity: 2-Critical
TMM crashes and produces a core dump.
Traffic is impacted while TMM restarts.
This issue occurs when: - You initially enable the transparent-nexthop setting on a virtual server. - You then disable the option. - You then disable auto-lasthop for the virtual server. - The virtual server receives traffic.
There is no workaround that you can instantiate to prevent this issue. However, if you are aware that you have already performed the necessary configuration changes to cause this issue to occur, and TMM has not crashed yet, you can delete the virtual server and recreate it (with the intended/final configuration) to prevent the crash.
TMM no longer crashes after modifying a virtual server as described under Conditions.
