kicked for violation 581, meaning?

I just saw a guy on my server kicked: kicked for violation 581
what does this mean? Ping timeout?

I think it’s the server thinking you’re speedhacking, It can be caused by lag, or getting stuck in your own door when closing it while walking.

It’s basically a miss match in data. Your client says you’re in one location and the server says nope.

If it is this then it nothing to worry about unless you’re actually speedhacking.

I just saw it disconnecting a user on my server earlier with that message, and got curious.
