sid verstrum commented: Had this problem on Ubuntu 18.04 LTS (GNU/Linux 4.15.0-20-generic x86_64), h2o deployed with Docker. The cluster would shut down at the first connection attempt from lynx (and Chrome): #P-Accept FATAL: missing eom sentinel when opening new tcp channel

The jar was being launched from absolute path java -jar /opt/h2o.jar

Changed to this: cd /opt java -jar h2o.jar

Solved the problem. Now monioring if it keeps alive 24/7.

UPD: have a feeling you may also have this problem when the networking stack is misconfigured. E.g. you run H2O in Docker with it`s own network. Docker is run in Ubuntu VM and you access h2o from the host OS. There is a plenty of room for misconfiguration here.
