My server was working fine but after a restart players lag terribly and and get an end of stream. It has been getting this error on startup for a while is this what is causing it? http://pastebin.com/j6L1ZX7A

edit-Now nobody can connect and it shows "Can't reach server" in the multiplayer menu when it is running

Computercraft loop. You could look through the computercraft folder and look at the code and see if you find someone's code which is an infinite loop that could be causing that (its semi normal to use an infinite loop for mob grinders but there is the risk of it bugging and doing this). Or you could just delete all the startup txt files from all the computers which would prevent them from running anything when they get loaded.

I wiped the entire folder and now I just get a readtimedout when trying to join and the server doesn't even show my player connecting, it appears as online for a few seconds then appears to go down after that and I still get the error on startup.

-edit- if you join right as it starts you lose connection 1 minute after that and can't re connect

Well there are very few ways to track it down as several items can cause that effect. Only thing I can really suggest is install tickthreading and set the deadlock detector to something like 1 min - 30 seconds and it can pinpoint if not remove it. Then you can remove TT if you wish (just remember to replace the files in backup folder into the main spot (will be your main jar + coremods)

I have installed it and it works (set deadlock to 35) however the server is still unresponsive and people can't join. I tried doing /tps or any other command in console and nothing happened it did not respond.
Error here http://pastebin.com/reubmeDy The server also crashed after a few minutes

Ok I moved to a dedicated server and my old VPS (had this issue just before I transferred all the data) works fine now but the new dedicated server is having these issues. Update- my old VPS just allows me to connect much longer than the new server but does not crash.

Well your tickthreading log shows what it is:

Code:
"Entities in Overworld/0 - 2", "Entities in Overworld/0 - 4" BLOCKED on nallar.tickthreading.minecraft.tickregion.TileEntityTickRegion@436e9706 owned by "Entities in Overworld/0 - 3" Id=108
        at nallar.tickthreading.minecraft.tickregion.TickRegion.run(TickRegion.java:32)
        -  blocked on nallar.tickthreading.minecraft.tickregion.TileEntityTickRegion@436e9706
        at nallar.tickthreading.minecraft.ThreadManager$2.run(ThreadManager.java:101)
        at nallar.tickthreading.minecraft.ThreadManager$1.run(ThreadManager.java:43)
        at nallar.tickthreading.util.FakeServerThread.run(FakeServerThread.java:16)

If it is a hostile mob you could probably just set the server on peaceful (the world as changing the server properties does not always effect it which would require level.dat editing) for a bit. If not then mcedit and delete all entities.

I do not have time to download the world and re-upload it and I can't find a NBTeditor for mac is there another way to fix this? I changed it to peaceful in the server.properties but still no, I tried /stoplag from worldguard and after 30 seconds it said it removed stuff but nothing changed.

if its responding to commands to /remove all 10000 from ingame (if you can) or if you can get ingame at all just set the server difficulty to peacefull while being on the overworld.

Now if you delete the forcedchunks.dat it should keep that spot from loading, but since you know its overworld via the thread trace you could just let people login untill the server stops and go look at where that player is at.

I have removed the forced chunks.dat but I still get a can't reach server and no commands from console work. Thank you for the quick reply as this is urgent.[DOUBLEPOST=1374868624][/DOUBLEPOST]I started it again and I think this is a new error (or more) http://pastebin.com/Ln71G7jX

Ah that new error is from a MFFS projector. That makes this a bit more tricky as you need to remove that block. Now you could remove MFFS and start the server up > stop > reinstall but all MFFS items would be gone. Considering it does not state what it was trying to calcuate which caused the error so in the modularforcefieldsystem.cfg you might try turning adventure mode on first and then remove all projectors.


Side note I am trying to remember how but I know there is a way via editing the block id to something like -1 in the config it will just remove that block but I am not completely sure about that.

Well its still seeing the projector as a projector so changing the ID for it does not appear to have done anything. You need to remove that projector just depends on how far you are willing to go.
