The root cause for SystemError: Failed to start Crate instance in time. (see https://github.com/crate/crate-python/issues/629) is that a previous instance of CrateDB might not have been terminated correctly.

In that case, a subsequent attempt to start it will croak like [1,2]

Caused by: io.netty.channel.unix.Errors$NativeIoException: bind(..) failed: Address already in use

Didn't see this for a while already. Even if, it's just a fluke. Closing this.
