Hi,
Without FLOWTABLE the system is stable an I was able to increase the
number of l2tp sessions. A major improvement came when I replaced the
network card with a multiqueue model (igb). The limit is now around 6300
active sessions. If I try to go over this limit the mpd5 starts to loose
old sessions and the number quickly decrease.
I believe I encounter an internal mpd5 timing issue. Is anybody aware of
such thing ?
!? 6300 ?!
when I wrote netgraph and Archie wrote mpd I think we were thinking in
terms of a few tens of sessions.
of course others have done a lot of work on both since then...
The server is now a dual xeon E5520 and the load is around 6.8 at peak.
The server has igb0 10.42.1.1/16 and 50 aliases.
My mpd.conf looks like this:
startup:
#configure mpd users
set user admin pass admin
set user foo bar
#configure the console
set console self 127.0.0.1 5005
set console open
#configure the web server
set web self 10.42.1.1 5006
set web open
set global l2tptimeout 60
