I'm having some issues running a KVM-virtualized FreeBSD 9-STABLE (somewhat four weeks old, so it has the latest netgraph code). I'm also running a 7.4-RELEASE (also virtualized) system on the same machine which has a way better stability record, although not stellar, but I think it would be way more interesting to find out what is keeping my 9-STABLE from being rock solid instead of relying on FreeBSD 7.4.
Right now it serves a 4000 clients network as a PPPoE server. There's also another six servers (non-virtualized), all running 7.4-RELEASE, serving the same network, so I can experiment with my 9-STABLE installation.
I will copy the stack trace from one of the four core.txt files I currently have. If requested I can copy more info, recompile my kernel with debugging flags to test etc. Just ask.
Thanks. Any help will be greatly appreciated.
