server keeps going down

hi my server keeps going down here and there expecially when using webmin

any idea on how i can fix this? the cpu load is also very low when it goes down

thanks!

 

It is pretty hard to determine what could be wrong from these informations. You should explain what happens when it goes down.

 

any time using webmin?

 

hey i am not exact sure what happens when it goes down... and also it dosent go down everytime i use webmin sometimes only, expecially when i heavily use it.

thanks

 

You might want to take a look at /var/log/messages to see if there is anything wrong there. Also having your vendor checks RAM again is a good idea

 

could not find anything in the logs...is there a certain file i should be looking at?

thanks

 

Server goes down same time everyday...or just anytime?

 

anytime, sometimes it will go down after 2 days or so

thanks again for the help

 

Based on the information provided there could several things causing this problem. You may want to have your power supply checked as well as the RAM. You also may want to keep an eye on the CPU temperature as many systems will shut down with excessive heat.

 

hey i am sure its not the power supply or the cpu temperature, because this is a virtual server on the main server but only the virtual server goes down

thanks

 

then it's totally different story. In that case you will need to check software you are using for controlling vps

 

As gate said with the information that it is a virtual server not a physical server, you will need to check the software you are using to run the VS.

 

Describe in detail "goes down". Does apache die, mysql? Some other thing happen? Does the server respond or does it need a restart.

Logs are normally inside /var/log/ folder. Read the logs associated with the function that does (i.e. mysql).

Are you in SSH watching TOP and processes while using webmin? Are you performing bulk actions on the server like log rotation or large mysql queries? You really need to tell us in detail.

 

Post your server specs.
Do you use a website that heavily rely on SQL?
Do you have web proxy on it?
Do you offer downloads?

 

i'm assuming you are hosting proxies?
proxies can make servers go down jsut like that on high traffic.

OR your site may be exposed to bots.

also check
tail -f /usr/local/apache/errors/error_log via ssh
