I gave a try on rhel7/rsyslog:latest(b98636a98907), the docker run w/ interactive mode will hang forever, and I can't get a useful debug information from docker logs, when tried to type ctrl+c several times, I got error like "rsyslogd: sd_journal_get_cursor() failed: 'Cannot assign requested address'", the test steps as follows:

1. run rsyslog container

# docker run -it registry.access.redhat.com/rhel7/rsyslog
Usage of loopback devices is strongly discouraged for production use. Either use `--storage-opt dm.thinpooldev` or use `--storage-opt dm.no_warn_on_loop_devices=true` to suppress this warning.


NOTE: docker run command hang forever.

2. open a new terminal window to check logs of running container

# docker ps
CONTAINER ID        IMAGE                                      COMMAND             CREATED             STATUS              PORTS               NAMES
3c0e51163d36        registry.access.redhat.com/rhel7/rsyslog   "/bin/rsyslog.sh"   41 seconds ago      Up 40 seconds                           hungry_poitras

# docker logs 3c0e51163d36

NOTE: nothing is in here.

3. back to above terminal window of step 1 and type ctrl+c several times.

^C^C^C^Crsyslogd: sd_journal_get_cursor() failed: 'Cannot assign requested address'
