error loop when someone gets disconnected

error loop when someone gets disconnected

msglm opened this issue 6 years ago · 15 comments

if someone gets disconnected for one reason or another this error happens on loop, taking up a lot of the ram.

I have discovered if someone gets disconnected via crashing, time out, etc it will start spamming the error.

TheRandomLabs · Answer 2 · 2018-06-11T01:41:43.000Z

Does this occur without RandomPatches? Because I've had this problem too, and I think it was to do with another mod.

msglm · Answer 3 · 2018-06-11T02:38:18.000Z

it does not occur with the mod removed, but this is also a major fix to my server because otherwise we get different errors. Sometimes the error loop gets so bad that I wont be able to type in the server console or input anything at all.

TheRandomLabs · Answer 4 · 2018-06-11T02:39:36.000Z

Alright, I'll have a look.

TheRandomLabs · Answer 5 · 2018-06-11T03:01:21.000Z

Can I have some more details? How much RAM have you allocated to the server?

msglm · Answer 6 · 2018-06-11T03:07:40.000Z

will send start.bat and modlist

TheRandomLabs · Answer 7 · 2018-06-11T03:09:59.000Z

Your Xmx is smaller than your Xms and you have a couple duplicate arguments. Your max RAM is 2048MB, but your minimum RAM is 5048MB. Also, I recommend not using 9Minecraft since they reupload mods without the authors' permission. Tinkers' Construct and Vein Miner can both be found on CurseForge.
Could you fix these issues and see if the problem still occurs?

msglm · Answer 8 · 2018-06-11T03:15:51.000Z

okay, I know 9minecraft is a re upload site and I used it in the beginning as I did not know much about modding. Exchanged vein miner with ore excavation (https://minecraft.curseforge.com/projects/ore-excavation/files/2552367) and tinkers with this versoin (https://minecraft.curseforge.com/projects/tinkers-construct/files/2568000).
swapped the values of the min and max of ram. About to launch and test.

Exception in thread "Server Watchdog" Jun 10, 2018 10:42:26 PM io.netty.util.ResourceLeakDetector reportUntracedLeak
SEVERE: LEAK: ByteBuf.release() was not called before it's garbage-collected. Enable advanced leak reporting to find out where the leak occurred. To enable advanced leak reporting, specify the JVM option '-Dio.netty.leakDetection.level=advanced' or call ResourceLeakDetector.setLevel() See http://netty.io/wiki/reference-counted-objects.html for more information.

This error has happended with your mod, I think the error loop was my fault.

TheRandomLabs · Answer 10 · 2018-06-12T12:16:53.000Z

If you're still having this problem, could you try 1.12.2-1.2.0.0?

msglm · Answer 11 · 2018-06-13T18:26:35.000Z

thanks man, going to try it out today. I hope it works.

This is still a leak that is happening.

msglm · Answer 13 · 2018-06-15T04:20:18.000Z

also the error happens but it does not loop.

msglm · Answer 14 · 2018-06-15T04:20:51.000Z

and this error seems to be happening, it is different

TheRandomLabs · Answer 15 · 2018-06-15T05:41:17.000Z

I don't think RandomPatches is causing these errors. BuildCraft is still in alpha, so you could make a copy of your server without BuildCraft and try running that instead to see if that fixes the problem.
