I do not know the data struvtures that James mentioned in any detail,
but speaking for the OS, we have certain data structures which are
allocated as memory resident during bootup only, so they can not
be 'cleared' while the system is up & running.

Speaking for the OS only (I do not have enough architectural understanding
of our networking code), I would consider any misbehaviour of software that
requires a reboot to clear things up at least a misdesign, if not a bug.

Usually though MPE/iX systems do not require any scheduled rebooting, unless
there is a problem (like depleting of some resource), and then the scheduled
reboot should only be regarded as a workaround until the problem is fixed.

I have BTW worked on 2 or 3 problems in the past few years that were
actually
worsened by the 'weekly' reboot cycle ... Looked like MPE prefered to be kept
up and running :-)
