Running Dev build #1522.

I've never had this problem before. My server crashed out. This is a serious issue and needs fixing ASAP. Please help...

Just happened again, still an issue. I THINK it's caused by DynMap taking all my memory? That's what I've come up with so far. I'm using the hidef(HD) render so I can see that as likely. I've turned off DynMap for the night to see if the server crashes then.

P.S: Sorry for the double post, but I really do need help on this...

Try disabling water-flow and lava-flow in your HawkEye config. It's been known to cause issues like this.

 

@c0mp They are disabled. :/

 

Then it could be Dynmap I suppose. Do you have it set to render on player-move or anything crazy like that?

 

Nope, but I do have it on hidef rendering. Maybe it's that? I've had it turned off for a while now and no random errors or crashes. So I'm 99% sure it's DynMap...

 

I don't have dynmap. Is there another solution? I host with daddycheese. Plugins (to my best knowledge):
AntiCreeper, Spout, Kingdoms, Heroes, PEX, PEX compat (permissions), ModifyWorld, Chatter, and a few more

 

It's to do with the server not having enough memory allocated as far as I know.

 

I fixed this myself. Your server must be packed with files and it is exceeding its 1024mb of dedicated RAM to that server. All I did was bump down my players allowed to connect at one time from 100 to 50 and I dedicated more RAM to my server and it started just fine. I know this forum post was created 2 years ago but if anyone needs the answer, give extra RAM to your server through this easy tutorial:

 

Yeah i had this problem but its easy to fix.
(Windows only)(64-bit only sorry those who have 32bit its not fixible with out more ram)

1. Hover over command prompt click edit.

It will come up with the code that you typed in once you first made your server to edit the ram

There will be a (number)-Xms
1GB = 1024
2GB = 2048
3GB = 3072
4GB = 4096<-----Thats were i am. Don't go to high if your not sure how much ram your pc has!!!!
12GB=12288

So edit the (Number)-Xms bit to one out of this list. Be carefull don't go past the limt of your computer because
i don' t know what will happen but im sure it won't be good .

Then just save it and start up your server! It might not work if it doesn't i'm not sure but it defently worked for me!
Thanks, I hope helped.
