    I've run a small server on a VPS machine to play with my friend. (which are 5-6 guys from my town)
    So I went with ubuntu and installed CraftBukkit 1.14.4 and few plugins (like WG, Worldedit, LWC, ETC)
    Till yesterday, everything was fine and we encountered no crash. Yesterday server crashed few times in a row. The crash dump was like this :

    I Did a search on internet, thought maybe its the memory (my VPS got 4GB of dedicated RAM and 2 shared cpu cores) so i changed the shell script to the following :
    java -Xms512M -Xmx2048M -XX:+UseG1GC -jar craftbukkit.jar nogui

    It was fine until now, when server crashed 2 hours within 30 minutes. Both logs can be read here :
    And the server console log before crash :

    I Am not an expert in bukkit or java so i dont know what this all means. Can anyone help me what went wrong?

    I Solved the crashes and mob stuttering (that were caused by setting max-tick-time to -1 and disabling watch dog) by moving from Craftbukkit to Spigot. Apparently Spigot handles mob farms and more chucks better than bukkit.
