Solved Random Crashes & Errors. (Caused by modified FramePicture)

Discussion in 'Bugs & Feature Requests' started by Dukecool15, May 28, 2015.

  1. Ever since I updated to 1.8.3 (updated to it on 5/8, now on 1.8.6) I've been experiencing random crashes with my server. (see 'Crash') And today I've noticed new stack traces popping up in my console. (see 'Error') It doesn't seem any plugins are involved in the crash or the error. Any help would be appreciated.

    Crash: http://pastebin.com/xkF6PnE5
    Error: http://pastebin.com/MMaAzXa6

    Using Spigot version: git-Spigot-6a6b839-b0e81a4 (MC: 1.8.6) (Implementing API version 1.8.6-R0.1-SNAPSHOT) (10 versions behind the latest build as of writing this)

    Edit: I've noticed the crash seems to occur sometimes when a player is logs in. (just today I've had my server crash twice, right when I was logging in.)

    Edit 2: Just get another stack trace in my console, but this time it was from Essential. However it was a 'ConcurrentModificationException' just like my other error & crash. (link: http://pastebin.com/tP5vMwsb ) Could Essentials be the one causing the crash? I am running a very old version (the first version that was released by the Spigot team for 1.8)

    Edit 3: I've disabled Essentials, gonna see if that fixes it.

    Edit 4: Confirmed. Essentials was the problem.

    Edit 5: Turns out the crashing continued even without Essentials. So I started disabling plugins one by one until the crashing stopped. I've found that the real cause is a modification I made to the FramePicture plugin.
