Problem What is going on with my server?

[drawingkid1313]

This happens at least once a week. Every time it has happened in the past, I just use a backup. (world is backed up automatically once every 24 hours)
I am running my server through a company called CubedHost. I don't think they change anything on how it works, and I have FTP access to everything, so nothing *should be* set up incorrectly.
Nothing really happens, it just crashes, kicks everyone off, and then won't let anyone on until a reboot.
Here is the crash report, I have multiple ones, so tell me if you wanna see another one.
The report made this post more than the limit of 10,000 characters. Because of that, this is only part of the report. I posted the full report on pastebin. Here is the link: http://pastebin.com/41eEE067

Thank you to anyone that helps.

I've seen a lot of threads with the same error but no solutions. I'm assuming it's just a bug in one of the mods that will probably be fixed in the next update. Are there any places where you're sending anything through a mystcraft or vanilla portal (other than players)?

Hmmm...I'll have to ask the other people on the server. It seemed to crash a lot when I was using the FTB Beta A pack without mystcraft, but I don't know if it was the same error.

How much ram do you have in your server that you can use?
I have the feeling you have 2GB RAM, and that you allocated all 2GB to the server, as soon as he gets over 1GB (windows) or 1.5GB (*Nix) the server will crash if you don't allocate it right

Yes, I do have 2GB. It should be fine, though. The server runs on some flavor of linux, and Cubedhost is a very reliable company that knows its stuff.
I keep track of the RAM usage through cubedhost's website and the most I've seen it go up to is 90% usage, so it shouldn't be crashing due to RAM limitations or anything. It is possible, and does make sense, though.

Just to rule it out, if you start the server with max 1.5GB (1500M) does it keep crashing then aswell?

Umm, I'm not too sure. I don't have that kind of control, and it might take a while since it's hosted by a company. I'd have to downgrade the server.

 

[Nessiroj]

not referring to the actual server, but the settings in your server.properties

 

[TheSandwichMakr]

I doubt that would have anything to do with it nessiroj because the issue he's having is that a mod is trying to reference index 677 of an array that only has 677 values so it's a bug with one of the mods which I'm assuming is mystcraft since there's a known bug about teleporting entities through portals and the issue happened when the server was processing the entities.

Got the same problem. But when i stopped every entity to go through a mystcraft portal the server stopped crashing.
