Hm... if this is the case then if I run another
program, it should be fine. But the
next program I execute will take an unusually long
time to execute..
eg. my program usually runs for 10 minutes but
now takes half a day, sometimes more!
I think that it has problems accessing the memory
as the swap will then start to be
in use. I don't think that 2 GB of memory if it is
accessible would be like that.

Nothing is wrong, you don't
seems to have a leak.
At some point, your system was using all but 10MB
of available physical
memory. The kernel doesn't release this used memory
until it's needed by
another program just in case you want to use the same
again to run the same program. This keeps the memory you
used ready to run your program again. You won't run out of
a program that requires more memory than what appears to be
This makes keeping track of how much memory is actualy free
difficult, but it is efficient.
