I have a socket server using IO::Socket::Async and Redis::Async for message publishing. Whenever there is a message received by the server, the script would translate the message and generate acknowledge message to be sent back to the sender so that the sender would send subsequent messages. Since translating the message is quite expensive, the script would run that portion under a 'start' method. However, I noticed that the Moar process eating my RAM as the script is running. Any thought where should I look to solve this issue? Thanks!

The issue was using the Async::Redis. Jonathon Stowe had fixed the Redis module so I'm using Redis module with no issue.
