As pointed out elsewhere I noticed the buggy behaviour of Arena randomly changing the configured hash table size.
After I stopped the tournament and looked at the uci settings of the 2 engines that were playing (Rubichess and Ethereal) I could not believe my eyes. Total garbage.

Did some further tests. It seems that playing pure eng-eng matches Arena 3.0 performs as expected, it keeps the 4Gb hash and after aborting the tournament the uci configurations of both engines are OK.
However as soon as you add a third engine to a (gauntlet or robin) tournament the trouble starts, Arena changing hash table sizes of engines and showing corrupt uci configurations.
Thorsten, are you reading this?

I am using 2.01 I never had any problems with hash.
It's not only a hash problem. In 3.0 as soon as you use more than 2 engines in your tournament it starts to mix up uci settings (see the pictures) with disastrous results for engines. Maybe you should check it out with 2.01
