problem: i allocated too much RAM solution: allocate at most 2/3 of your machine's memory so in short i made a new server & never crashed while i was "doing" it, i opened the server for public 2 days ago and it crashes randomly. the server already crashed like almost 10 times in less than 24 hours. i checked every log before it crashed, and none of them show an error msg, the server just shut down (screen is terminating on putty) Hosting: Vultr VPS 4GB (Singapore) OS: Debian 9 x64 (stretch) Memory: 4GB My Java version: Spoiler My Startup: Spoiler Log before server crash (actually its from server startup until crash, since it sometimes happen every 10 mins or so): - https://pastebin.com/ZZhBdPqf - https://pastebin.com/kvtmfXzz [/spoiler] My plugin Spoiler Things i did before this random crashes happened (ones i remember): Spoiler - adding SkinRestorer plugin (& disabling CMI skin) - Disable "fly" flag with /rg, on my PlotSquared generated world - Updating this plugin & change the "enable world" : Spoiler https://www.spigotmc.org/resources/dont-break-the-block.66852/updates - Disabling Built in Paper xray (since it seems not working) - Installing OreReplacer plugin (now uninstalled because it apparently replaced most of the diamonds on my server) - Instling Orebfuscator4 (by the times i installed this, the crashes already happened, i dont really remember about the rest above) - change the value of WildStacker's config: from 300 to 500 This is a new server and i got some old online friends playing, and some of them started leaving because of the crashes. Any help would greatly be appreciated. thank you in advance.
