I don't think that's good idea, like what would we know? Would we have
to wait 30 times longer, so month-3months, to hit what ever it is,
before we have confidence?

I would suggest
 - turn on debugging, to see cisco emitting LACP PDU, and juniper
receiving LACP PDU
 - do packet capture, if at all reasonable, ideally tap, but in
absence of tap mirror
 - turn off LACP distributed handling on junos
 - ping on the link, ideally 0.2-0.5s interval, to record how ping
stops in relation to first syslog emitted about LACP going down
 - wait for 4days
