Try removing newrelic for your app if you are using newrelic. Newrelic rpm gem itself leaking the memory. I had the same issue and I stratched my head for almost 10day to figure out the issue.

Hope that help you.

I contact newrelic support team and below is their reply.

Thanks for contacting support. I am deeply sorry for the frustrating experience you have had. As a performance monitoring tool, our intention is "first do no harm", and we take these kind of issues very seriously.

We recently identified the cause of this issue and have released a patch to resolve it. (see https://newrelic.com/docs/releases/ruby). We hope you'll consider resuming monitoring with New Relic with this fix. If you are interested in doing so, make sure you are using at least v3.6.8.168 from now on.

Please let us know if you have any addition questions or concerns. We're eager to address them.

Even if I tried update newrelic gem but it still leaking the memory. Finally I have to remove the rewrelic although it is a great tool but we can not use it at such cost(memory leak).

Hope that help you.
