If the browser is running always, the device probably starts to run
out of memory.  You could automatically restart the browser each night.

Builtin apps only spend disk space, not RAM.  Making more space on
internal flash could save some RAM from internal JFFS structs though,

There's a D-BUS API for this use e.g. by mediaplayer.
You need to call it once a minute I think.
