This is a linux question not an asterisk question. I have seen very
recent threads on here which explained what was happening and why, you
should try to review them.

I think you will find that if you reboot and don't start asterisk,
over-night your memory usage will increase to around 500M.
Most likely, during the night is when your cron scripts run, some of
these traverse the entire filesystem (update/locate) and prompt the OS
to save some of the FS contents in memory (ie cache).

In any case, it is normal to use almost all of your memory. If you
really have doubts, then look at ps aux which will show you memory usage
per process.

And, this is unlikely a asterisk problem and more an OS
mis-understanding.

Adam
