Error Thats Crashing Server Randomly

So, i ran a server for 5 days now, and this last 3 days, server always crashed randomly, sometimes every 15 minutes, sometimes not crashed until 12 hours.

Right before it crashed, i always got this exact same error message on the console.

29.09 09:03:18 [Server] SEVERE at net.minecraft.server.NetworkWriterThread.run(SourceFile:104)
29.09 09:03:18 [Server] SEVERE at java.io.DataOutputStream.flush(Unknown Source)

29.09 09:03:18 [Server] SEVERE java.net.SocketException: Socket closed
29.09 09:03:18 [Server] INFO Read timed out

I think this is some kind of network/firewall probel am i right ? It's hosted on a hosting company so i cant make sure about it. I have asked the staff, they said disable plugins. I did that, still same errors.


Anyone knows how to solve this ?
