Please Help, Server Lagging And Crashing Whole Time!!

Hello Bukkit!

I own 150 slot server.
PvP Faction Mcmmo and other stuff.
Ip is play.ageofelysian.nl
So problem is that server lags and crashes whole time.
And i really need figure out what is wrong.
When i start server, i get some errors but not much, when server is started, i dont get errors.
It crashed sometimes and lags alot as i said. When server crashes, i dont get any errors, it just crashes. And i need restart in multicraft.
I attached picture where is list of plugins.
Now i was again running server, i restarted, 2 min and again crashed and was 10 people online.
Server has 5gb ram and 21 plugins. I think some of the plugins makes this.

I hope that someone reads and help me out.

And i get in console whole time:
[WARNING] Can't keep up! Did the system time change, or is the server overloaded?

In multicraft CPU usage is 6%
And memory usage is 30%

Here is errors:
And other plugins starts fine so i didnt copy those above this errors.

 

Bukkit version?

A 150 slot server on 5GB of RAM is a bad idea, it should be ~60-70 slots at most.

What you quoted is not an error, it is 'INFO'.

 

List the 21 plugins?

 

MineIRC, Multiworld, Groupmanager, NoCheatPlus, WorldEdit, iConomy, Permissions, Permissions, Buycraftm Lockette, Vault, AntiRelog, Votifier, mcMMO, worldguard, AntiCreeper3, TopPvP. Essentials, EssentialsSpawn, MasterPromote, EssentialsChat, Factions


And i just have 150 slot, i havent anyway had more than 30 now. And everyone leaves because server crashes whole time. And we have 2 map, nether and world.


GC when is one player:
Maximum memory: 4,919 MB
Allocated memory: 4,919 MB
Free memory: 3,538 MB
World "world": 555chunks,121entities
Nether "World_nether": 625chunks,121entities

 

It looks like you are running 1.3.1 . Try downgrading to 1.2.5.

 

Really? Downgrade? Well i didnt have problems in 1.2.5 so i think its because of new plugins or this bukkit.

 

1.3.1 is not officially 'out' yet. It's a development build, and it's very, very unstable. Most of the plugins are not updated for 1.3.1 yet. Just downgrade to 1.2.5, and wait until your plugins are ready for 1.3.1, and Bukkit has an official RB for it.

 

Now i got errors when crashed!

1.3.1 is a dev. build for a reason! It isn't ready to be released to the public officially, but they still put it up for download if others want to use it.
Always except issues with dev. builds.

EDIT: What is your startup script?

 

Idk, i have host from nitrohosts and multicraft control panel.

 

Downgrade to 1.2.5 !

 

I want to say that startup script doesn't have --nojline at the end...
