Rancher host has to be rebooted every couple of days

Hi there -

Having something of an issue with Rancher. The Host is a 1GB host on digital ocean and rancher is the only thing running on it, memory usage is at 5% but the JVM is throwing an out of memory exception, the server will not accept connections and the reverse proxy returns a 503. If I hard reboot the server (eg. reboot now) the machine will come back up and rancher will be “game on”. But it’s annoying to have to go in and reboot the server every 3-4 days.

When I try to restart just the container, it locks and will not restart the container. The only way to recover is to reboot the host.

Any advice would be most welcome. I’m running rancher:latest as of 6 weeks ago.

Thanks in advance!
