Bug ID 627621: TMM restart loop following 'bigstart restart' on i2x00 and i4x00 platforms

Last Modified: Apr 11, 2023

Affected Product(s):
BIG-IP All(all modules)

Known Affected Versions:
12.1.0, 12.1.0 HF1, 12.1.0 HF2, 12.1.1, 12.1.1 HF1, 12.1.1 HF2, 12.1.2

Fixed In:
13.0.0, 12.1.2 HF1

Opened: Nov 09, 2016

Severity: 1-Blocking


On the BIG-IP i2x00 and i4x00 platforms, TMM enters an infinite 'restart' loop after a 'bigstart restart' or 'bigstart restart tmm' command if traffic is actively flowing through the TMM.


System is unusable due to continuous TMM restarts.


Traffic actively flowing through the TMM and you issue 'bigstart restart' or 'bigstart restart tmm'.


Ensure all traffic is stopped before issuing the 'bigstart restart' or 'bigstart restart tmm' commands.

Fix Information
