freebsd stable - Jul 2003 - Reproducable panic with multicast on VLAN interface

Hi,

I have a problem with FreeBSD-4.8-STABLE in which the system panics when
multicast definitions are being removed from an interface. The later is very 
easily reproduced by killing zebra.

This is a rather serious problem because it makes FreeBSD unusable as a VLAN
router in a data center.

I filed a PR for this including the traceback (kern/54314), but on examination
of the gnats database I found that this problem was also reported in 
(kern/40723) with a more accurate problem description than mine.

I would like to resolve this issue but I do not know how to proceed: can
someone help me with this and do they need more info to do so? Or is there
are detailed description of this part of the kernel available, so I can look
for the bug myself?

Thanks for any advice.

Frank

Try my patch which I posted to freebsd-bugs last month.

Indeed this fixes my problem as well!

I hope it will be integrated into the CVS tree soon.

Thanks for you help.

How about attaching that to one of the PRs open on this bug?  Maybe
someone will commit it then...
