Can you open an issue in the issue tracker? There are some differences in the way logging is handled with a
tty attached, and without, but I'm not sure where these would come from.
\0000 is unicode for
NIL, but it's a bit strange that's being logged.
When opening the issue, please provide the output of
docker version, and
docker info, and it would be great if you could provide some information about the image you're running (if public), and how (with what options) the container is started.
Note that for logging, it's recommended to set a
--log-opt max-size and
--log-opt max-files so that log files are rotated (to prevent your host running out of disk space.
