This means the player is moving faster than the server. It Is unfixable (aside from getting a faster server)
It is not only related to RAM. It is also related to TPS, your network speed, players' network speed, etc. You can use PocketMine-Soft to disable it, but it may cause other problems.
Actually the latest builds of Soft removed the only way to remove it. :/ I am sticking to old builds.
Some People say that in the old Version it means,that the Players are to fast for the server!And for the new Version some people say when a Player go over a slib!
I found out the problem and pointed it to @shoghicp. It is a problem with Jenkins's build of PocketMine-Soft, that a conflict happened with the source. Use the latest Jenkins build #237, which fixes the issue. This build fixes the interaction-angle thing too. Magic goes here. https://github.com/PocketMine/PocketMine-Soft/commit/7993d8327a44ea16ad8f13539e2e46698f62de12
