Severity: 3-Major
An incorrect configuration on an irule associated to a BigTCP virtual server can lead to TMM to core.
Traffic disrupted while tmm restarts.
The following circumstances are needed: - BigTCP Virtual server - FastL4 profile with syncookies enabled. - Invalid iRule that will fail to execute, on LB_FAILED - Syncookie currently activated in that moment.
Correct or remove the irule event and coring will no longer occur.
TMM now correctly handles the specific scenario to no longer core.
