--- Comment #2 from Donald Baud <donaldb...@yahoo.com> ---
We started using mpd5.8 (netgraph l2tp) with FreeBSD RELENG-10.3
This is a replacement to a cisco7206 npeg (LNS)
Terminates about 300 l2tp tunnels, 800sessions and 800Mbit/s
I noticed several unresolved bug reports relating to crash with netgraph:
Bug 199096 Kernel panic after some time using mpd (netgraph) and ipfw
Bug 176401 [netgraph] page fault in netgraph
Bug 154286 [netgraph] [panic] 8.2-PRERELEASE panic in netgraph
Bug 154091 - [netgraph] [panic] netgraph, unaligned mbuf?
Bug 153497 - [netgraph] netgraph panic due to race conditions
I don't want to start an new PR but I'm noticing many panic's, once a day
mostly:
I've experimented with net.graph values but did't do any difference:
