Last Modified: Nov 07, 2022

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

Known Affected Versions:
11.6.0, 11.6.0 HF1, 11.6.0 HF2, 11.6.0 HF3, 11.6.0 HF4

Fixed In:

Opened: Jan 14, 2014

Severity: 3-Major


When the TMM is low in memory and HTTP is configured, the configuration process may initialize a new HTTP parser. If that initialization fails, then the TMM may crash.


Traffic disrupted while tmm restarts.


A virtual containing HTTP is configured or re-configured when the TMM is under extreme memory pressure.



Fix Information

Configuring a HTTP filter during extreme memory pressure will no longer cause the TMM to crash.
