I actually thought this "Basic-Table" was inactive. It is not so I'm going to
deactive it now. Since it was holding > 200k routes, this is for sure a lot. Doing that
made the syslog message disappear but it didn't actually free up as much as I was hoping for:
GOT: Jtree memory segment 0 (Context: 0x44976cc8)

Still doesn't look to glorious, right?
Best,

Can you paste the output of these commands:
show conf | display set | match rpf-check
show ver
show route sum
DPC should have enough memory for ~1M FIB. This can get divided in half if you
are using RPF. If you have multiple routing instances, this also can contribute
to the problem.

I furthermore found this article on Juniper KB:
http://kb.juniper.net/InfoCenter/index?page=content&id=KB19015&actp=search&viewlocale=en_US&searchid=1236602855555
Is it really possible the MX480 cannot handle more than roughly 500k routes in
the FPC? What are my options here? Do I have to upgrade the SCB + get some new
interfaces modules in order to keep this box running?
What are my options to get some time? Where is the right knob to aggregate
routes (if that's a good idea) to - let's say - /23?
Thanks in advance!
Jeff
