Hi brahs,

Im online in my server (now the little) and I use the command !uptime to check. Fine! I get 32 hours online of uptime in my server and without problem and without explanations my server put down! Puff, down!

The strangest part is..., when the server down i dont get rollback in my character. Other players said for me that lose any items but is strange because i haven't seen players complain about anything.

So, ive 3GB of ram to run 3MB of Map! Dont have any script automatically to crash or requiring machine memory (+)

Im pretty sure that whoever closed the server was the machine. How can I get an answer on this? Getting more ram?!

When was happened have 75 players online.

How I do for the machine never suspend the server?

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
713 root 20 0 498m 293m 8084 S 26 9.7 50:36.20 tfs

Using 26% CPU & ram 9.7. With 70 players online. It is bad?

This can help someone in something and better interpret my situation? cuz I don't know what these messages mean.

My server down was 21h50 at Nov 22. I found that:
PHP: 
Nov 22 21:50:07 localhost-51 kernel: [1641251.039574] tfs[31453]: segfault at ffffffffffffffe8 ip 00007f1a654d7e29 sp 00007f1a62b511f8 error 4 in libstdc++.so.6.0.13[7f1a65430000+f6000]

No bro, the server went down without reasons at twenty days ago and I found out it was for lack of ram. I bought a better dedicated, with 3GB of ram. Okay! The problem of downs are fixed! So, today, im online in my god and check the uptime.. was 32hours and he down! just that.

There is online at 3 hours and 32 minutes without problem.. But i think that will happen again, but not with a given time.

So, check that: http://pastebin.com/1BAUvWxz
I think it will help in something..

@Limos Did you can try to help me, bro?

Run the server in GDB and then show us a back trace of the crash. If the server is using alot of memory after a long period of time it could be a memory leak within the server source code or a script that is not well made.

I have tested. It is a memory problem. Isn't any scripts. The server is original.

I want to know how to fix that:
PHP: 
Nov 22 21:50:07 localhost-51 kernel: [1641251.039574] tfs[31453]: segfault at ffffffffffffffe8 ip 00007f1a654d7e29 sp 00007f1a62b511f8 error 4 in libstdc++.so.6.0.13[7f1a65430000+f6000]

I try to find solutions in web like that error:
PHP: 
error 4 in libstdc++.so.6.0.13



Anyone know?!

I would suggest doing a server restart every 24 hours if it's a memory leak..
When you wake up every day, just do a server restart, or just before bed. -shrugs-

No, because I can not allow my server fail all the time or at any time. Not memory problem because 3Gb ram to support a map that weighs 3mb and a daily amount of 60-100 players n' has no automatic script or any type of event that causes the server need a large memory index. This not problem for this machine. My server works with distribution of items vips, he cannot fall because people would take advantage of these unexpected drops to clone items and this would bring the server to bankruptcy.
