MC-Server on Raspberry Pi

[Luksor]

Short question:

anyone experience the following error:

-unable to connect if server restarted with 'restart' command

-digging up snowballs with a shovel let the client crash

Greetings.

I'm unable to recreate this bugs.
Restart command works for me and breaking snow with a shovel drops a few snowballs.
I was testing on Windows, so It's probably a Raspberry Pi issue.
