I miss the message when containers stop/die. I assume they are written under DEBUG log level, but the level should be INFO since you report "started" messages under INFO. Thus currently it is not possible to estimate the average lifetime of a container.

Besides

I see that containers are spawned like crazy. It's been 17 hours since the torture started. Thus I have an impression that the scaling algorithm went wild. Are there any cold period tunables? How can I debug the reason why it happens? Will DEBUG log level help?

I propose to add the reason why the container is killed or restarted - e.g. a scaling decision or a panic/segfault. No need to be verbose, I want smth like

time="2017-09-11T10:12:09Z" level=info msg="container stopped bblfsh/java-driver:latest (01BSR6SG97GW4TBW4NWB7FPB94) - oops" time="2017-09-11T10:12:09Z" level=info msg="container stopped bblfsh/java-driver:latest (01BSR6SG97GW4TBW4NWB7FPB94) - scaling"
