[!HELP!] Server Crash -> Netty Crash and Internet Crash

[Bektor]

Hi,

 

I just played a bit on my test server for my mod with a friend and then the server crashed...

 

What I did: just removed some of my gravity blocks (a few hundred) which resultet in a few more hundred EntityFalling blocks and then the complete internet connection of my house was gone....

Restarted the server, did the exact same again... same result... No idea why this happens cause nothing in the log before this happened shows anything related to my mod and I don't even call any netty methods, so I think this is caused by Forge or Minecraft (or something else?).

 

A few hours before I had even a crash that because of so many falling entities the netty thread crashed... I still don't know why this happened... but I don't think this should ever happen.

 

Netty Crash-log:

BlockCollapse.java:45 -> calls a method and results in BlockCollapse.java:54 --> calls a method which results in BlockCollapse.java:127: on that line is just the 'continue' keyword inside of a while-loop... No idea what's going on there....

Unfortunately there isn't any more information and my router can't tell me anything else because I had to reset it to get the internet back, but windows told me in the fourth try to locate the problem something about an invalid ip-configuration while the router was online, but no device in the house was able to get a connection to a website or the router itself...

 

I hope this is the correct forum and someone can help me with this!

 

Thx in advance.

EDIT:

Forge Mod Loader version 12.18.1.2094 for Minecraft 1.10.2

Java is Java HotSpot 64-Bit Server VM, version 1.8.0_101, running on Windows 10:amd64:10.0 (Anniversary Update)

 

Installed mods other than mine:

BiomesOPlenty-1.10.2-5.0.0.2085-universal.jar

worldedit-forge-mc1.10.2-6.1.4-dist.jar

 

The server started with these flags: JVM Flags: 2 total; -Xmx4096M -Xms4096M and in the nogui mode.

 

If more information is required, please let me know how to provide them, cause this is everything I found which is related to the problems and saved in a crash-log or/and log file.

 

EDIT 2:

Could also re-produce the netty crash with a huge amount of gravel blocks.
