I'm using way more memory than is allocated for me by the virtual machine hosting service (limit is 512MB with 1024MB burst). I checked what is running using the top command and found that I have two large apache2 instances, each clobbering 277MB. Why two? Also, MySQL should have very little work to do but still uses 144MB.
Am I doing something wrong? Can I force these processes to be more frugal?
Note that unfortunately I can't create a swap disk or file, the VPS doesn't support that.
Following is what top tells me (sorted by memory usage):
