CPU usage goes to 100%

[Moriarty]

I'm using a Amazon EC2 m3.medium ( more than enough resources to host a ragnarok server )

My cpu usage never goes more than 10%, however some times it sudenly jumps to 100%, and then my char-server can't save anything in the database, and nobody can log in.

I've already opened a ticket on amazon support, but, maybe this can be a rAthena problem, so i'm posting here too.

Did anybody have this problem too? Or i'm a first? haha
If you have any ideas how to solve this, it will be much apreciated.

 

Oh, by the way, with 100% cpu usage, players still connected to map-server can play as if nothing happenned, players offline can't login, and nothing is saved on database.
I can still log in on the cloud, open phpmyadmin and stuff

If I restart the server, everything goes back to normal, so I guess that maybe there is really an issue.
Oh, and i'm not complete sure that 100% cpu usage is the cause to char-server down, maybe it's the other way around.

This is my normal usage: http://puu.sh/a2mwt/4a1fcbb636.png
When it happens again, I will take a print of what is using 100%.

how much RAM do you use?

rathena running good with 1GB RAM

[Moriarty]

I Have 4GB, as you can see in the pic, it uses only 800MB, RAM is not the problem.

[Winz]

could be there's something wrong with your script, file, or others that leads to infinite loop, makes server re-calculates, therefore CPU usage -> 100%, and the rest thing.

not only the script, others as well

I'm having the same problem!

Verify this map 1@ma_h and warp.

 

The map-server up to 100% of CPU and Freeze.

 

Soluction:

 

coment the line: in maps_athena.conf

//map: 1@ma_h

[Moriarty]

HOLY SHIT, it's true o______o

Only this map? Maybe something with instances, will test others

THANKS MAN

I found another map with the same problem: poring_c02

[Moriarty]

Yeah, it hapenned again with my server this night.

There may be other maps too.

[comsamo]

It still happen to me. Any ideas?

[Norm Hmuryj]

You need to check your PC, because one map cant be the reason of freezing.

[Moriarty]

You need to check your PC, because one map cant be the reason of freezing.

Yes it can, and it was.

By the way, not the map, but the npcs on that map.

The problem is solved, althouth my friend is having the same problem and he have already disabled the bangungot hospital instance D:

[comsamo]

OMG still happening my server..

What i missing? T^T

[Moriarty]

Yeah, there is another thing causing it, don't know what.

[Winz]

I guess this should go to the bug section, then
