Server keeps crashing every 30 minutes.

I run a pretty large server, MCHollowed.com, and about every 30 minutes it crashes with no errors. No errors in console what-so-ever. It seems to crash every 3rd save. My plugins are:
AutoAnnouncer
CFBanner
Essentials
EssentialsSpawn
Giant Trees
HawkEye
HeroChat
Item Detector
LagMeter
LWC
MagicCarpet
MaintainenceMode
MobDisguise
Modifyworld
NoCheat
PermissionsEX
PluginList
ServerSave
VanishNoPickUp
WorldEdit
WorldGuard
I have updated all my plugins to there latest version, regenerated config files for all of them, in console everything seems fine, I am getting no errors. Any ideas on what could be crashing my server?

 

Do you get Read timed out errs in console?

 

Since a crash is fairly disruptive, you may want to temporarily remove all but the most necessary plugins. You may have have a conflicting or bugged plugin. Did you check your server log? Some managers (like McMyAdmin) won't give you full console details, assuming your not looking directly at the console when it crashes.

 

@tombik I am not getting read timed out errors in console.
@Killburner I was looking directly at the console and it just became unresponsive and before you say it, I do not think it is a DDoS because my server is located in a data center.

 

Allocte more RAM to your server, maybe that helps?

My host is Mutliminecraft, I bought 8 gigs of ram from them and they have top of the line processors. Don't think that is the problem.

 

Maybe contacting your host can solve problems? because I don't think you do anything wrong? unless you have plugin problems but as you said, it stops without any error. Think that's a problem with the host.

See I have moved hosts 3 times because of this problem and with every host I have had the exact same problem. MultiMinecraft's software and hardware is amazing so I really can't see it being a problem on there end. Also I got rid of some plugins, so now I am only using:
AutoAnnouncer
BuyCraft
CFBanner
Essentials
EssentialsSpawn
HawkEye
HeroChat
LagMeter
LWC
MobDisguise
ModifyWorld
NoCheat
PermissionsEX
ServerSave
WorldEdit
WorldGuard

 

I had the same issue this morning. I got rid of Citizens and OkModTicket and it seemed to fix it. I think one of the plugins could be bugged. I would see which ones you recently added and go from there.

 

backup the current world, start CraftBukkit without any plugins installed and see if the problem persists, if so re-download the jar and try it again

 

Maybe you can get your server to localhost and test some stuff? always delete a plugin untill it works fine so you can put the fix live?

The crash times now vary between 10/20/30 minute intervals. The world saves every 10 mins. Is there a saving error with the RB?

 

I use the RB now for as long as it has been promoted and used 1.0 dev builds before and I have 99% uptime so I can only think about a plugin issue at the moment. And the only way to solve that is by disabeling the plugins one by one I'm afraid =S

edit: so I never used hawkeye but I know it's very CPU needing. Try first without that one?
