Rails App Memory Leak: Nginx + Unicorn

Question

While testing my app with Jmeter i found that the memory consumption is increasingly high. After running htop i found it very strange that there are two master processes and that each worker process has many childs.

My question is: is this normal or is this possibly the reason for the memory leak (or bloat)?

Answer 1

There aren't two masters, it's an htop feature/bug :)

About memory consumption: why do you have so many workers? I see 29, 30, 31... you shouldn't have more workers than CPU amount, the only effect would be a used memory increasing. Try with 8 workers (I see you have 8 CPUs)
