My initial reaction is, this was pilot error.

JunOS works by default like IOS with 'soft-reconfiguration inbound'. I.e. all
routes you've received are stored, filtered or not.
And I would imaxine the EX not having memory to receive all routes, so you
likely simply exhausted your control-plane DRAM and left the system in rather
unpredictable state.

You could configure 'keep none' in JunOS to stop storing filtered routes and
you likely should be able to receive full table just well and cherry-pick what
routes you're interested in.
