Hi. I have a 128MB Virtuozzo-based VPS, running Debian Sarge. As I understand it, RAM on these VPSs for the 128Mb flavour is burstable to 512Mb.
When I checked to see how much memory was free (since after a restart I needed to close some overtaxing processes), the results seemed wrong. Am I just misinterpreting the output of the commands? top output is at pastebin.ca/277219.
I'm confused because it shows the amount of total RAM as 362.537MB with 19M RAM and half a meg of swap space used. Is the amount of memory being reported incorrectly? If so, what negative effects would that have on VPS operation? Last, how should I address this?
3625376 kilobytes is roughly 3.5GB. It looks like your VPS is showing the total RAM and swap for the entire server. Since it is Virtuozzo, you can run 'cat /proc/user_beancounters' and see what your memory allocation is - look for the 'vmguarpages' and 'privvmpages' entries. Take the "barrier" entry for each and divide the numbers by 256. The vmguarpages is your memory guarantee and the privvmpages is your burst.
