IGMPProxy stops when ppp tunnel goes down

[malkie123]

Hi, i want to use it to forward multicast via pptp. In general it works but as soon as one client disconnects igmpproxy crashes with the error

ioctl SIOCGIFNETMASK for ppp0; Errno(99): Cannot assign requested address

This happens only if used with the option rescanvif which I would need to forward the traffic to new clients without restarting igmpproxy. Any advise? Here is my config:

rescanvif defaultdown

phyint eth1 upstream ratelimit 0 threshold 1 altnet x.x.x.x/x

My ppp interfaces are the downstream interfaces which are recognized automatically. Whenever a tunnel disconnects it crashes.

Thanks

Malkie

Can you please post gdb backtrace (or corefile) of the crash?
