How to deal with Ruby 2.1.2 memory leaks?

Question

I have a worker process which spawns up to 50 threads and do some async operations (most of which are http calls). When I start up the process, it starts with some 35MB of used

Answer 1

I'm author of digest/murmurhash and digest/stringbuffer gems.

Indeed, It seems like have leaks in digest/stringbuffer.

I'll fix it later.

Can you explain more code?

I recommend using singleton methods like this.

Digest::MurmurHash1.hexdigest(some_data)

Maybe, It's not leak since singleton methods are not using digest/stringbuffer.
