I currently have a website running on Slicehost. It is running the MySource Matrix CMS which does take up a fair amount of resources. Every once in a while, I get an alert from slice host saying that my swap usage has been very high. And, when checking my site, it is crawling, sometimes not even able to visit it. So, I have to reboot the server and the site is back up and quick.
I did make a setting in Apache for max users as someone said that this might help. But I am getting worried when it happens like this. We really only have about 150 visitors a day, so it is not really a too many user issue, I would not think.
Currently I am running the 256 slice. What can I do to ensure that this does not continue to happen?
256 Slice Debian PHP5 Apache 2
