Server Crashes when not in Peaceful

Resolved
Awaiting Response
2

The problem:

Anytime I'm online with other players, and the game is set to Easy, the server lags out, and crashes. It appears to be eating a lot of memory before the crash.

The conditions:

When It's just one player, server runs fine.

When two or more players are in close proximity, the server runs fine.

When the game is on Easy and it's daytime, the server runs fine.

When the server is on Peaceful, the server runs fine, regardless of distance between players, and non-hostile mobs.

I've tested locations other than my island. Distance appears to be a problem regardless of location.

The two other players tested it in my absence, and with sufficient distance, the server crashed.

I've tried ggservers and virtualgladiators for server hosting, and both have this crash.

I have had this issue since at least 19w04b. I have not tried earlier snapshots or 1.13.2

Attached is the most recent crash report.

 

Thank you,

I'm also noticing some mining lag at night. Peaceful mode, just me on.

Having the same issue in 19w06a. The server starts to heavily lag when more than one player is in the server and eventually crashes due to one tick taking 60 seconds. Problem is fixed when the difficulty is set to peaceful mode.

Server crash log:

Sounds like you might have the max spawn rate in the server settings set too high, when all hostile mobs start spawning the server cant keep up

Is this something that can be changed in vanilla Minecraft? We're only using the snapshots and as far as I can tell I can't modify the max spawn rate. I attempted to lower the view-distance to see if it would help at all, but it didn't.
