Server geht nicht richtig an

Hallo Leute,
Ich habe seid gestern ein Problem. Wenn ich meinen Server für die CraftBukkit Version 1.8 starte komme ich normal in die Warteschlange. Nach einer weile startet dann der Server. Aber das steht die ganze Zeit dann da Ich versuche mit Minecraft auf den Server zu gehen aber das geht nicht. Auf der Seite steht immernoch das er startet. Irgendwann ist er dann einfach offline. Wenn ich die CraftBukkit Version 1.9 installiere dann kann ich normal mit 1.8 drauf spielen
Es währe nett wenn ihr mir helfen könntet
LG: EnderMinerLP
