Affected Product(s):
BIG-IP vCMP
Known Affected Versions:
11.3.0, 11.4.0
Opened: Feb 19, 2014 Severity: 2-Critical
The TMM might restart continuously and report 'TMM thread (20) greater than max (16)' in /var/log/tmm.
The TMM does not start, which prevents the system from going online or passing traffic.
This issue occurs when a vCMP guest is deployed with more than 16 CPUs.
You can use one of the following to workaround the issue: a) Lower the cores-per-slot attribute to a value of 16 or lower. b) Inside the affected guest, issue the commands: 'bigstart disable tmm', 'setdb tmm.threads 10', 'bigstart enable tmm', 'bigstart start tmm'.
