If a BIG-IP VE license enforces a number of TMM instances less than the system would otherwise run, and that license limit is not a power of two (e.g. 1, 2, 4, 8, 16), the BIG-IP system will incorrectly start with a non-power of two number of TMMs.
This results in traffic disruption and connection failures where traffic leaves one TMM, but returns and is not processed by a different TMM.
Certain license combinations can result in the BIG-IP VE system starting with a non power of two number of TMMs.
Set the "provision.tmmcount" DB key to the next lower power of two (1, 2, 4, 8, 16) from the count listed in the license.
None
