(PM) BRIs on OR-U/PM2 revisited

Since we had a debate last week about the lack of stability of the BRI
interface in ComOS 3.7 and this week I actually got to telnet into a router
that had screwed up as a result of the memory leak in ComOS 3.7, I thought
I'd pass along the debug info I got out of the box.

Obviously, I passed this info along to support@livingston.com, but if
someone from Lucent RABU reading the list can shed some light on what this
means (especially the sh isdn and sh isdn d0 commands), I'm sure it would
help the cause.

This OR-U (and a few others I have in the field) do this all the time - run
for a few days and then leak memory which eventually causes the BRI to go
"NO SERVICE" and the only way to get it back up and running is to reboot the
router.
