I did enabled KDB, DDB and WITNESS on the same sources. Unfortunately there was just plain hangs once some GRE was trying to get through (netgraph? PF? routing?) With these options enabled, hangs are much more often than without them. Once hung, no way to break into debugger, no panics, numlock not changing lights on keyboard, mouse not responding, hdd silent, network not available, nothing. 3 different HW platforms were tried (all of them were UP+i386+32bit). Highest CPU temperature was 52C. No chance to go with 7.2-PRERELEASE. Had to downgrade to 7.1-RELEASE. /dennis 2009/4/11 Max Laier : > Is it possible for you to turn on WITNESS on this machine to obtain possi= ble > LORs that might be responsible for the hang? =C2=A0Also, do you have the > possibility to enable DDB and drop into it from the console (if it is not= a > hard hang but a live lock)? > > -- > =C2=A0Max > --=20 Dennis Melentyev ___ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"

Although I can't afford to restore the configuration to test the issue, but I feel, that problem could be connected to IPv6 + PPTP/GRE/PF/IPv4. The machine we've tried to connect from was running Vista. AFAIR, it tries to make some use of IPv6. Can't tell anything on XP or other clients - never tried that. OTOH, outgoing PPTP (IPv4) session from MPD4 to some HW VPN router (sorry, anonymous to me) was just fine. Hope this helps. I can't upgrade ATM, but still can supply config files if needed. /dennis 2009/4/15 Dennis Melentyev : > Hi Max, > > It was some hard time for me, sorry for late response. > > I did enabled KDB, DDB and WITNESS on the same sources. > Unfortunately there was just plain hangs once some GRE was trying to > get through (netgraph?

I had no PPPoE. Only PPTP connections. One is outgoing VPN to ISP and 10 incoming VPNs for employees. Also, my configuration used to have two uplinks with extensive use of policy based routing and forwarding. daemons: mpd4, pf. It is possible that I have some kind of loops in routing, it was not very professional set-up :) BTW, I have no possibility to reproduce the problem since I've downgraded system to 7.1. /dennis 2009/6/8 Bohdan Tymkiv : > Dennis, > maybe this issue is related to > http://www.freebsd.org/cgi/query-pr.cgi?pr=134557 > can you confirm this? > > -- > Bohdan Tymkiv > > -- Dennis Melentyev ___ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
