So I just moved to a new host that I thought will be better then the last one because it has more CPU power.It turns out I was wrong. On my old host I had 4GB of RAM and when I did the /mem command (from the plugin Essentials)it displayed the maximum memory at 4025 MB, the same as the allocated memory. On my new host I have also 4GB of RAM but when I do the /mem command it displays the maximum memory at 1508 MB and the allocated memory at the same amount.I asked my host and it said that he allocated 4 GB of RAM to my server and that the command will still say the same amount.Is my host fooling me? Let me tell you my story...I ran the current server with 5/64 players online and the server crashed with Java Out Of memory errors.The odd thing was that MultiCraft said that the memory usage was only at 56%. I run the almost the same plugin like on my old host(i had LogBlock there and I don't have it here and now I have MultiVerse running 5 worlds including nether and end and only 2 worlds have the spawn left in memory).I could run the server with 40+ players on my old host and there was little lag but now even with 5 players there were HUGE lag spikes of 10-15 seconds sometimes. And this was the error that spammed my console when the server crashed: Code: 2012-04-17 17:08:48 [SEVERE] java.net.SocketException: Software caused connection abort: socket write error 2012-04-17 17:08:48 [SEVERE] at java.net.SocketOutputStream.socketWrite0(Native Method) 2012-04-17 17:08:48 [SEVERE] at java.net.SocketOutputStream.socketWrite(Unknown Source) 2012-04-17 17:08:48 [SEVERE] at java.net.SocketOutputStream.write(Unknown Source) 2012-04-17 17:08:48 [SEVERE] at java.io.BufferedOutputStream.flushBuffer(Unknown Source) 2012-04-17 17:08:48 [SEVERE] at java.io.BufferedOutputStream.flush(Unknown Source) 2012-04-17 17:08:48 [SEVERE] at java.io.DataOutputStream.flush(Unknown Source) 2012-04-17 17:08:48 [SEVERE] at net.minecraft.server.NetworkWriterThread.run(SourceFile:103) So should I blame my host for not allocating me 4GB of RAM or is MultiVerse that memory intensive to crash my server with 5 players online out of which 4 were in a world and 1 in another world?I got to mention that one of the worlds is the same as the one on my hold host(where only one player was at that moment).
