Guys may be I didn't stress the point of distribution stuff well. I agree with you all but if you see my first post 3rd line. May I am bit afraid that our discussion side tracking actual question.
Its my fault I didnt explain well. - AKKA is NOT causing GC problems ( our application is in production from last 6 or 7 years, it is written in Java) - With my (current team) interest towards and akka and scala slowly introducing stuff - As we are moving towards akka direction we are encountering different challenges. One among them is what I specified over here. - We are not taking akka advantages such as scalability and fault tolerence etc.. We are using just for broad cast messages between 3 JVMs (one among them has 880 GB heap space and 1 TB ram) I can not change infra all of the sudden. As a developer I suggest them about distributed advantages but decision is not in my hand. I hope I explained well.
