After some minutes the players doesnt see me on tab and my body on server!

I have to reconnect to fix this

(no i was no vanished.)

Can you give me the steps to reproduce this as well as your spigot and essentialsx versions.

Spigot version: git-Spigot-db6de12-3f3c65f (1.8.8)
EssentialsX: #268 http://ci.drtshock.net/job/essentialsx/

sorry the problem was the skinsrestorer, now fixed!
