Subject: leakage of sockets or  activerecord connections
Date: Fri, 23 Aug 2013 00:13:36 +0200	[thread overview]
Message-ID: <52168D10.8080407@corinlangosch.com> (raw)


I'm using rainbows to power my own small middleware. I doen't use rails (or any 
other framework), only activerecord for database access. I chose 
XEpollThreadSpawn, set worker_processes 1 and worker_connections 25. All classes 
are eager loaded, no reloading of anything while the server is running. AR 
connection pool size is set to 100.

Now it seems that every request opens a new connection and never frees/ closes 
it. So after 100 requests I get an AR connection pool exception. I also see 
exactly 100 postgresql clients connected. When I kill the server all clients get 

I wonder if I have to setup and hooks (like in unicorn before_fork etc.)? In 
fact I'd expect this happens automatically as the thread exits after the request 
is completed?
