Hey guys, I've made a FTB Revelation server for my friends and I to play on. For a good amount of days it worked fine but lately it started crashing, there's been 3 crashes yesterday alone, and I honestly don't know why. I have no idea how to find out what causes it, so I thought maybe you guys could help me decipher any possible cause and clues?
Here are three of the crash reports I got, I saw something about Advancemets in the third one so I turned them off via gamerule:

The server runs on a standalone PC stripped of any program, with 5GB of DDR3 RAM dedicated to it and an i5 4590S, Windows 10.

Any help is appreciated. Thank you very much ^^

I have the exact same problem. I can confirm this was not an issue in 3.2.0 and is present in 3.4.0. This issue seems to happen when chunks are being generated rapidly and the console is being filled with messages as follows:

Code:

Then the watchdog kicks in and kills the server which is deemed hanged.

I am running the server on Debian 9
