> Number of cores - 3

> I am using streaming on the production for some aggregation and fetching data
> from cassandra and saving data back to cassandra.
> I see a gradual increase in old generation heap capacity from 1161216 Bytes
> to 1397760 Bytes over a period of six hours.
> After 50 hours of processing instances of class
> scala.collection.immutable.$colon$colon incresed to 12,811,793 which is a
> huge number.
> I think this is a clear case of memory leak
