How to remove a set of IAtmoicLong counter from Hazzle cast memory

I am creating multiple IAtomicLong based counter dynamically in Hazzle cast for a requirement. I would like to know if I am creating multiple IAtomicLong based counter will it create any memory related issues like OOM ?

If so what is the option I will have in removing the counters from hazzle cast memory at particular interval of time.? I checked for any TTL(Time to live) setting in IAtomicLong and was not able to find one.
