Troubleshooting

Unresponsive Server

We noticed on some Linux servers entropy shortages leading to unresponsiveness. To use the entropy from the host system, add /dev/urandom:/dev/random:ro to volumes of the wildfly service in the file docker-compose.yml:

services:
  wildfly:
    # ...
    volumes:
      # ...
      - /dev/urandom:/dev/random:ro

If even the entropy from the host system is not enough, you might have to install a random number generator to feed the linux random device like haveged.
