More info
I've tried disabling the ServerHangWatchdog, though same issue is present.

The crash is a watchdog crash. That, unfortunately, means that whatever was running at the time appears in the crash log... not necessarily the thing that is actually causing the problem.

If you've tried disabling the watchdog then what happens if you do?

If I disable the watchdog it just stays frozen until it eventually turns off.

Ok figured.
I afraid is not much I can do for you.

The crashreport indicates a setup with an RFtools builder inserting items into a Dank with an external storage attached. I don't think that would be particularly laggy.. But like I said chances are it's not what is causing the actual issue.

To figure that out you would need to do some profiling with a program like Visualvm.

It's most likely a deadlock
