And... on correctly working kernel, it is, right?
If you have no swap space and too many applications, you plug more memory. (Or invent some swap).
If you misconfigured cgroups, you give more memory to them.
If your applications mlocked 900MB and you have 1GB, you need to plug more memory.
So... when is plugging more memory _not_ valid answer? AFAICT it is when it is some kernel problem, resulting in memory not being reclaimed fast enough.... Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
