Hi! Imagine your server is running well, no laggs,nothing and suddenly (doesn't matter if the server is empty or somebody is only) it is overloaded and gives out strange messages.

Restart--> All player data was gone! I (the owner) joined as newbie! Thanks god there are backups. The overloaded-thing happend the second time, so dont know why, but this is normal, still annoying, but can be fixed with reload. (random part) The second error with that java stuff and the player data happened the first time. Is this a bug, or dou you think Grizzly_f hacked the server? (crazy new part) Plugins: TimTheEnchanter, GroupManager, WorldEdit, NoCheatPlus, WirelessRedstone, Vault, MobBountyReloaded, WorldGuard, AntiNyan, MineBackup, SpawnerAdjuster, ChestHarvester, iConomy, Permissions (the list is from /plugings. I haven't foound a permissions.jar and can't remember installing this,so I think you can ignore that), BKCommonLib, FalseBookBlock, EssentialsSpawn, LWC, Monster Apocalypse, FalseBookIC, ChestShop, EssentialsChat, FalseBookExtra Bukkit version. Beta 1.2.5 R3 Need more informations? Ask! Mfg mojo_blaster
I'm afraid I don't know how to help your problem but the reason it says permissions there is because of EssentialsGroupBridge.jar
oh,thanx i noticed, that the server-performance got a little bit worse. the chunks are loading slower,but not much. maybe theres a connection. EDIT by Moderator: merged posts, please use the edit button instead of double posting.
Your server needs more memory. Either you have a lot of players, or lot of worlds, or both. The problem is, that server tries to load a chunk and it can't load it because it has memory leak. To give server more memory, increase the number after -Xmx in your launching command("java -Xmx1G -Xms1G -jar craftbukkit.jar"). For example use -Xmx2G instead of -Xmx1G . Increasing number after -Xms also helps.
i dont think so. the "cant keep up" messages started while there was no load on the server,no player was online,nothing. so why should there be not enough ram if it always worked an i remove some plugins? i gave the server under 1 g (around 600-700mb,cant remember), cause the virtual machine i rent at strato only got 1 gb ram. it worked always, so why should there be suddenly in the middle of the night without anyone online not enough free ram? and does this explain, why all user data was gone an we were all newbies instead of builder/moderator/owner ??? its a bug of the r3 beta, i noticed that it happens since ive got the R3 beta. but im not sure. maybe something else is the reason, that slows down the server.

Oh, anyone was online! Then, it seems to be something around MineBackup and R3 beta. My friend had similar problem too, but it was fixed by resetting(not reloading) the server. I suggest you set minebackup to only do backups when someone's online. It's more efficient, saves HDD space and also a little bit of RAM.
i think ive already set that things in the config a month ago. i saves no hdd if you define to only leave 8 backups und delete the rest im testing beta r2 at the moment, lets see what happens tried beta r2, still doesnt work, but the erro log is a little bit different: 2012-05-13 08:14:09 [SEVERE] Exception in thread "Thread-49167" 2012-05-13 08:14:09 [SEVERE] java.lang.OutOfMemoryError: Java heap space 2012-05-13 08:14:12 [SEVERE] at java.nio.HeapByteBuffer.<init>(Unknown Source) 2012-05-13 08:14:14 [SEVERE] at java.nio.ByteBuffer.allocate(Unknown Source) 2012-05-13 08:14:14 [SEVERE] at sun.nio.cs.StreamEncoder.<init>(Unknown Source) 2012-05-13 08:14:17 [SEVERE] at sun.nio.cs.StreamEncoder.<init>(Unknown Source) 2012-05-13 08:14:19 [SEVERE] at sun.nio.cs.StreamEncoder.forOutputStreamWriter(Unknown Source) 2012-05-13 08:14:21 [SEVERE] at java.iutputStreamWriter.<init>(Unknown Source) 2012-05-13 08:14:23 [SEVERE] at java.io.FileWriter.<init>(Unknown Source) 2012-05-13 08:14:23 [SEVERE] at com.Acrobot.ChestShop.Logging.FileWriterQueue.run(FileWriterQueue.java:24) 2012-05-13 08:14:26 [SEVERE] at org.bukkit.craftbukkit.scheduler.CraftWorker.run(CraftWorker.java:34) 2012-05-13 08:14:28 [SEVERE] at java.lang.Thread.run(Unknown Source) 2012-05-13 08:17:03 [SEVERE] Exception in thread "Listen thread" 2012-05-13 08:17:07 [SEVERE] java.lang.OutOfMemoryError: Java heap space 2012-05-13 08:18:23 [SEVERE] at java.io.BufferedOutputStream.<init>(Unknown Source) 2012-05-13 08:18:49 [SEVERE] at net.minecraft.server.NetworkManager.<init>(NetworkManager.java:56) 2012-05-13 08:18:55 [SEVERE] at net.minecraft.server.NetLoginHandler.<init>(NetLoginHandler.java:29) 2012-05-13 08:22:07 [SEVERE] at net.minecraft.server.NetworkAcceptThread.run(NetworkAcceptThread.java:47) EDIT by Moderator: merged posts, please use the edit button instead of double posting.
