Cannot deploy stack

Up until yesterday I was able to deploy stacks both through rancher-compose and through the UI (by uploading my docker-compose.yml and rancher-compose.yml configurations).

I am running rancher server v1.6.6 on the same server as a single host (running docker v17.03.1-ce). Shortly after running rancher-compose up -d, I observe the following logs for the rancher server (through docker logs):

I also notice that the scheduler (v0.8.2) crashes, with the following logs:

I’ve also noticed that, on startup of the server, I get the following logs which I have not noticed before:

time="2017-08-11T15:25:59Z" level=fatal msg="Error getting config." error="Invalid key content"

and

time="2017-08-11T15:26:00Z" level=warning msg="Couldn't load install uuid: Get http://localhost:8080/v2-beta: dial tcp [::1]:8080: getsockopt: connection refused"

Any ideas why this might be happening?

Thanks,

Please ignore this, I found the source of my problem: some services in the stack mount large volumes, and docker’s data directory was filling up and causing rancher and my other services to crash.
