Well that's what the default was, I just ran it and that's what it gave itself. Anyways, I ran it in Command Prompt and gave it 1GB and it still did the same thing. I guess what I'm also trying to say is that it's not just about the crashing, it's the high tick rate. Why is it higher when running a server? When I run the client, it works near perfectly, but the server can't handle 1 person being on it without it's tick rate flipping out. It's also annoying breaking a block and waiting a few seconds for the server to catch up.
I'll attach another crash report of putting it to 1GB.
Like I said, I thought that too. That's why I tried it on my Windows 10 computer which has 2GB of RAM and a 2GHZ processor. It still did the same thing. I'll attach it's crash report too.
Crash report is for Raspbian OS.
Well the other thing is that it'll run a 1.7.10 server flawlessly, but once I put it back to 1.9, ticks went up and crashed. Actually, It runs a 1.7.10 forge server with 17 mods and runs between 100-300 milliseconds, so I'd imagine that even with some additions from 1.8 & 1.9, it shouldn't run any faster then that. But maybe that's just me...
