Re: Memory Leak? (repost)

linux kernel likes to keep things in ram to keep things fast, there's alot
of cacheing going on.  i wouldn't worry about it unless you start hitting
swap heavily without doing much of anything.  my light use server is using
128mb of swap (512mb of physical memory),b ut there's not much going on.

nothing to worry about, i'd worry if you saw individual processes using
alot of memory (use 'top' to find this out, you can sort by different
criteria.  press 'h' for help or look aot the man page)

Understatement of the century:
"Hello everybody out there using minix - I'm doing
a (free) operating system (just a hobby, won't be
big and professional like gnu) for 386(486) AT
clones"
         - Linus Torvalds, August 1991
