As first Improve your RAM size, your core gets lag with it.

Second, your cores can't connect db or whatever (depend your ports).

There's something freezing your server at that moment. Can you check your server's date?

[Rumor 2537]

how much RAM do you have? It's pretty hard to get a dedicated server that doesn't have enough for a metin2 server. How many cores do you run too?

[AlCapone 67]

I have 4gb ram and only run 4 cores in total for 2 chanels on...So whit 4 cores i think is ok and only 60-80 players..

It's okay those lags appear when some connection for example db to game or game to game take too long.

Restart the Auth Server and make sure every ymir server check or expiration date is removed before you do so.

Also check if you get attacked and check if the connection to mysql and other connections are fine

Oks thanks I will intent that and coming whit news.

Thanks guys I really like this forum , helping users

[Rumor 2537]

yeah doesn't sound like a ram issue

[Shogun 4464]

I had the same problem in my server and it turned out to be a hardware issue which caused the system clock to be off.

Always make sure your server's time is correct.

[Rumor 2537]

yeah just use NTP hahah

[AlCapone 67]

Ok one question how I can see the server time )?

If you haven't got ntpd running, use the ntpdate command (with any time server) to set the clock:

ntpdate time.kfki.hu

Can you tell how I make all that whit comands etc

Thanks

I recommend you don't use NTP, block it or disable it if possible.. alot of ntp attacks going around lately.

How i disamble it

Thanks a lot for all

[Rumor 2537]

ee /etc/ntpd.conf

uncomment:

restrict default ignore

As far as I know this should do it.

 

Could also try this next:

service ntpd stop

The first step is enough to secure against ntp attacks, if you disable ntpd you can't sync your server's clock automatically and this is a very good idea when you are running a metin2 server where the clock going off can cause big problems.

[ATAG 309]

Mutch better to make a firewall rule to access the ntp port only by the timeserver.

[AlCapone 67]

Thanks a lot guys problem resolt was for that time I disambled and now server works on perfectly.
