Severity: 3-Major


In the unlikely event that HSB drops off the PCI bus, TMM continuously restarts until the BIG-IP system is rebooted.


Repeated TMM restarts. Traffic disrupted until you reboot the BIG-IP system. The HSB reappears and is functional after reboot.


The conditions under which the issue occurs are unknown, but it is a rarely occurring issue.


Manually reboot the BIG-IP system.

Fix Information

TMM no longer gets stuck in a restart loop, as a reboot is now automatic in this scenario.
