Hi all, I found this PDF from Hiroki SATO, which quotes MPD5 as PPPoE server with IPv6. I wonder if anybody has already successfully tested DHCPv6 with Prefix Delegation ? Regards.

Yes ! no more more crashes observed. We still have some strange PPPoE incoming request : Sep 8 05:27:06 bng1 mpd[23657]: Ignored incoming PPPoE connection request via ix0_1515: for service "" due to bad length 28172 > 40 Sep 8 05:32:03 bng1 mpd[23657]: Ignored incoming PPPoE connection request via ix0_1515: for service "" due to bad length 204 > 40 Sep 8 05:57:33 bng1 mpd[23657]: Ignored incoming PPPoE connection request via ix0_1515: for service "" due to bad length 24588 > 40 Sep 8 05:59:05 bng1...

Hi Eugene, here is the status : 1) done 2) done 3) waiting for future crash Fyi, we have 2 servers running MPD5 and the process crashes at the same time on both servers, we are suspecting a malformed frame. We will provide backtrace info asap. Stay tuned.

Hi Eugene, it happened again : Sep 1 20:01:21 bng2 mpd[1334]: caught fatal signal SEGV Sep 1 20:01:21 bng2 mpd[1334]: 0x28438e <???> at /usr/local/sbin/mpd5 Sep 1 20:01:21 bng2 mpd[1334]: 0x283ffa <???> at /usr/local/sbin/mpd5 Sep 1 20:01:21 bng2 mpd[1334]: 0x80077ab70 <_pthread_sigmask+0x530> at /lib/libthr.so.3 let us what you need to investigate, thank you in advance.

It works much better with FreeBSD 12.2, thanks ! I will post this issue on the right forum.

We use mpd as a pppoe server, it accepts pppoe requests from several vlan interfaces on 10GE NIC. We have around 400 ngX sessions. We upgraded from 5.8 to 5.9_1 on FreeBSD12.2 today, we monitor it to check if crash happens again, we will let you know.

I've tried this but got "ipfw pullup failed" messages on console and system freeze with sometimes kernel crashes on FreeBSD 13.0, any idea ?

Hi Eugene, I will test BSDrp1.99 which has MPD 5.9. Is there some debug option to enable on mpd ? log +all is enough ?
