I'm running Teambox community edition on an Ubuntu Server machine, with 600Mhz and 358MB of RAM. I know it's not much and that's probably the cause of all the trouble I'm having, but maybe someone knows another solution.
The thing is, I'm running Unicorn as a Rails server, using 2 workers (more would just clog up the ram completely), and they work perfectly when they're up and running. But after about 15-30 minutes (I think), the workers' RAM usage drops a lot, and if I try to reach my Teambox installation, it takes forever to load, and most of the time the request will timeout showing me an ugly "Proxy Failed" screen.
I'm connecting to the unicorn workers using an Apache Proxy.
