Server crash and filling up the ram

Since 31.12.2011 for 3 days now I can't fix my sevrer.

We are experiencing server crashes at random time - 5 to 50 minutes after the server starts.
At a random point it starts filling up the ram pamet and then starts pininging out all the users.

The spec's of the PC are 12gb ram, 4 core pentium i5. The sevrer was running more then 6 months with no big problems, but this time we are nto able to fix the problem becouse it doesn't pop out anything in the console. It just starts filling out the ram untill it crashes.
If I remove all the plugins it is ok.
I tried to remove all the plugins but not PermissionsEX but it still crashes. it could be the Pex plugin.
Can you give me advice for another plugin that supports MySQL storage and is reliable/uptodate?

From time to time it pops this:

Code:

[INFO] Fetching addPacket for removed entity: CraftItem

Idk if it is related to the issues we are experiencing or not.

I tried also to reinstall the MySQL, it didn't fix up the problem.
Reinstalled Java also - still it crashes up.

The problems just started at 8 a.m. on 31th, with no changes made to the server.
We tried with new, blank, worlds but the problem continues.

 

Does it still happen if you remove only PEX and no other plugins? If not, post on its BukkitDev page and see if anybody else has the same problem. Also make sure you have the latest version of PEX.

 

So basicly the problem is not in PeX.
It is some software bug.

I reinstalled the OS - Windows 7 and the problem was fixed.
2-3 days later the problem happens again.
I just installed FireFox and went to twitter.com and then Bum crash.
Idk if it is connected or not, but the only fix I found out is to reinstal the OS => it is some software bug.

Last time I tried to reinstal java, mysql, etc. but it didnt fix the problem.

Please is there anywho else with problem like mine who figured it out?
I don't want to reinstal my OS every 2nd day...

 

Are you using any anti-virus or firewall software?

 

Nope dear sir.
After the reinstall I puted only java, mysql, skype and chrome.
Nothing more.

 

If it is not affecting your gameplay at all, then you generally do not need to worry about it... especially as it is only an [INFO] message

 

Dude. The server crashes every 5-15 mins. Read the whole topic

 

Bah, sorry about that; Was just reading a topic with the same error where they mentioned they weren't having any issues because of this.

Do you ever use TNT on your server?

 

Is windows firewall disabled? Or an exception add to it for the server?

 

@Tyler_Tsero The firewall isn't disabled, it's the default windows firewall with add to firewall options. Also I am pretty sure the problem isn't in firewall. Please read the whole topic. The problem is that from time to time it starts to fill up the whole ram and then crashes. It is like on 3-4gb's of ram and then sudenly it goes to 7-8-11 ram for 3-4-5 mins.

@Pezmantbh we use TNT blocker plugin that disable TNT usage.

Any other ideas?

 

Try turning off animals and monsters in the server.properties file

 

@Pezmantbh Many people will go mad if I do so becouse they make animals in animals farms...
You think that they might cause the problem?

 

Disable them for a while, and see if it fixes it. If not, re-enable
