Ticking entity...?

Hi guys,

for some reason, I've been experimenting this problem for a couple of hours withut having changed anything in my server.
Whenever a concrete player joins the server, the server crashs with the following message:

Code:java

2014-10-21 00:25:27 [WARNING] Can't keep up! Did the system time change, or is the server overloaded?

I've done a research in google about that "tricking entity" and I've tried already done the things that other people with the same problem did like scanning my world with Minecraft-Region-Fixer, whitout success. Also, there aren't any strange entity in the area where our problematic player spawns, like custom mobs or thing like these.

Any help will be appreciated,
thanks in advance.

P.S: Banning the player isn't an option.

 

Pitazzo Your server seems to be running out of memory. How much ram do you have set to your server? it is possible you have some sort of memory leak. I would recommend try launching with default minecraft server and see if the problem persists.

 

tcvs My server has 5Gb of RAM memory, and there was just one player online. There are a lot of plugins, including my own, whuch is a little bit heavy, but for months it has been more than enough.

I've to say that we use a custom minecraft client which needs to preload some cache brefore leting the player join the server, and the client of that concrete player who causes the crash takes a lot of time to join, actually, when the server crashes the player wasn't able to join yet.

Thanks in advance.

 

Pitazzo So are you working on a modified server?? I think it might have to do with that pre check then. Can you try connecting with the normal client?

 

tcvs yeah, that was my next option, but I have not been able to contact with the player yet. If you're interested, the client is just Spoutcraft.
