Hi Didi,
There are three, unless there are more I am not aware:
Defined memory - which I am trying change
Max allowed - which was auto increased
Guaranteed - which was also auto changed, but I set it to 4096

There are different parameters around memory - are you sure you change
the correct one(s)?
Also adding Arik. Arik - please see the history of this thread. It
might be an issue in the engine, or in hosted-engine HA, or both - not
sure.

No idea. 4.3 is past EOL now. I suggest to try latest 4.4, and if it
reproduces, file a bug and attach all relevant logs (including engine,
vdsm, hosted-engine-ha).
