In some scenarios on BIG-IP Virtual Edition (VE) platforms, TMM may crash due to backplane inconsistency shortly after a provisioning change.
TMM may core with panic and post the following message in /var/log/tmm log: 'Unexpected backplane address'. Traffic disrupted while tmm restarts.
- BIG-IP VE with performance-limited license. - Additional licensing/provisioning of modules raises performance limits. New TMM processes are started. - No reboot has occurred after provisioning.
Reboot after provisioning if new license add-on keys raises performance of the BIG-IP system.
TMM no longer crashes after provisioning if new license add-on keys raises performance of the BIG-IP system.
