INFO com.oath.halodb.Uns - OHC using JNA OS native malloc/free Out of memory!!!

I got a logging info INFO com.oath.halodb.Uns - OHC using JNA OS native malloc/free Out of memory!!!
Why does that information come up? How can I change the Java Memory configuration ?

Could you please provide some more details; how much memory is available on the box you are running HaloDB, how many keys are you storing and what are the size of keys. Also have you enabled the memory pool ?

HaloDB stores all the keys in an index in memory for fast lookups, therefore we need to make sure that there is enough memory for all the keys.

@ShuaiJunlan - how many keys and what is the structure of average key you use?

Thank you for answer.
