Sorry to disturb you, but I notice that some memory is not freed even after
restart.
For example, suppose memory usage is 400 MB. I make server restart and it
still 400 MB. Processes are not killed. After some time, more memory is
used and webfaction kills everything.
So, I think overall memory usage is not a problem, the problem is that
memory is not freed. Can you explain why?
