All sounds like a bit of Broadcom to me :-).

Looks like its replacement is the 5120 series. The question is does the 5120 have the same limitations and similar chipset?

    To echo Alain's comments earlier, the Juniper QFX 5100 series is
    stable, once you figure out all the shortcomings of the chipset. 
    We aren't doing anything fancy, but have certainly bumped into our
    share of issues that have no workaround because it's a limitation
    of the physical hardware.  Since we're talking about counters, see
    if you can spot the error with IPv6 accounting in the output from
    our 5100 below (about 50% of our traffic is v6):

    ;-)

    I believe the 5100 just announced EOL
    (https://support.juniper.net/support/eol/product/qfx_series/
    <https://support.juniper.net/support/eol/product/qfx_series/>); I
    haven't had time to look at the replacement models to see if they
    behave any better.
