#2

if anyone could help i would really appreciate it


#3

UniverseGuard is having problems creating a region, ask the author/report this to them


#4

Ok thank you.Will report it to them


#5

It’s possible that universeguard was stalled too long, but this was just the last thing that the server was doing on a tick that exceeded the watchdog time.

Either the watchdog is faulty, or something was causing an intense amount of lag on the server.

Judging that it was BlockDynamicLiquid, I’m guessing a large liquid spill or world edit operation or something inside a universe guard handled area.

This could either be a non-issue (reprimand your mods / admins to make smaller edits, and disable the watchdog(worldedit can cause the server to stall and boot people, but it usually finishes eventually), think about setting limits to world edit sizes)

Or could be indicative of a performance issue inside Minecraft/Forge/Sponge/UniverseGuard or your server.


#6

I have the same issue and i dont have universeguard in and it happens to me when creating a world fresh installs dont fix it or anything. Please help im not sure if its a sponge issue or what.


#7

Add more RAM to the server. For me the /warp command was the issue. Adding more RAM to the server fixed it
