>Description:
I run four PPPoE network access servers based on
FreeBSD 8.2-PRERELEASE/amd64 and mpd-5.5 (/usr/ports/net/mpd5)
that extensively use NETGRAPH. Machines use very different hardware
but same software: they are NanoBSD-based and loaded with same disk image
and nearly same configuration (just distinct IP addresses).
All servers panic under heavy load when they have 900-1800 PPPoE clients
connected and more than 500Mbps going from uplink to clients
and more than 500Mbps going from clients to uplink same time.
All panics are pretty similar: that's GPF when mpd is active process.
I've got full crashdump for total 4GB of router memory.
Here comes gdb backtrace. Then dmesg output, kernel config file,
boot.conf and sysctl.conf.
