[j-nsp] VC ports not working until they are reset

Hello,
After reboot of our QFX5100 / EX4300 Mixed virtual chassis we lost connection
to several units. We can see the VC-Ports being up but they cannot see their
neighbor.
We deleted the Ports 1/2 of fpc4 and reset it as vc-port. After that the
connection worked again. The same has been done two times more with several
other connections to get a fully working virtual chassis again.
We see this quite often, nearly everytime we rebooted one of our VCs on
different VC.
Does anyone else notice such a problem with VC ports? This does not seem to be
a physical problem because the ports are working after they are being deleted
and set again as VC port.
After bootup:
