Memory maxing out on forum
 
OK, so our server had to be rebooted the other morning because we'd maxed out the memory. This is the first time this has happened so im looking at whats best to be done.

The server hosts have suggested we upgrade to a bigger memory package.I am wondering if there are practical things i can do this end first.

Is there a way we can work out where most of the memory is going? Are there things that can be deleted that won't then return 404 errors?

Thanks

What host are you with?

ozzy47 06-12-2014 09:57 AM
Server and site specs would help also.

2GB RAM
2GB vSwap
100GB Disk space
3TB Bandwidth

Or another great vps deal (which I've never used yet):

Also there is a way to tell what's using up memory on linux but I forget the method atm. I'll post back if I find it.

Run the top command and you'll get results like this.

Do you have any caching mechanism installed, like xcache? If not, do that and install vboptimize before you switch hosts.

And, yeah, see what is taking up memory like final kaoss mentioned. It's either mysql or apache.

Thanks mate, thats really helpful. Gonna take a look at those. clearly better specs. My only concern is we are uk based and we'd be hosted in the states. Would this be an issue?

I believe the latency between UK and USA is somewhere between 50 and 100ms, so you can expect such delay added to your HTTP requests. Personally, I wouldn't buy a host based in USA when my customers are from UK.

This should be able to help you with it.

Why do you think the server is maxing out its memory, and why does your host think that?
