If memoryleaks are your problem, then better try to fight them. Until 
they are beaten, better reboot the entire system as there are more 
programs running 'forever', which might have a memory leak...

To do you regular reboot (or any other maintenance script) you'd better 
schedule it with the backend. It has an entry to shutdown the system 
once it is finished. You'd better use that entry to initiate the scripts.

That's where these entries are used. At least have a look how and where 
they are doing things.

The 'nightly' fill of the myth database is (as far as I know) also 
triggered on myth backend startup (or at boot at least).

For summertime, (when you fancy an airco) you'd better switch the system 
off, like they do at the acpi wakeup page.

You did not join the army I guess.
