    Hello all!

    Recently, I have been running into some lag issues on my server.

    For example, I get many "Can't keep up!" messages in my console (once every 20 seconds) and the TPS shows 6~15 when I do /tps. This never happened before, and it started when I installed a plugin called PlotSquared. I uninstalled the plugin, but the problem persists. I have 31 plugins, and 8 worlds.

    /tps:

    Uptime: 13 minutes 27 seconds.
    Current TPS = 13.99
    Maximum Memory: 4,607Mb
    Allocated Memory: 4,607Mb
    Free Memory: 3,682Mb

    Can anyone help me with this?

    Thanks!

    EDIT: The server crashes after around 2 minutes of starting it up, so I set my Maximum Tick to "-1" in the server.properties file to disable watchdog.

    Code:

    This only happens when someone is on the server, and "Can't keep up!" messages do not show when nobody is on.

    Have you already deleted the PlotSquare folder in /plugins/? And how much GB ram have you bought?

    WARN Can't keep up! Did the system time change, or is the server overloaded? Running 5845ms behind, skipping 116 tick(s) Is a pretty normal error that can be because u have too many plugins or there is alot things on the ground

    31 plugins and 8 world is a lot.

    To support this memory, you need to purchase more MB/GB for your server. If you cannot upgrade, try and reduce some of your plugins.
