That's strange, after recompiling the lastest 8_0 that contain the patch ( http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/rpc/clnt_vc.c.diff?r1=1.8.2.2.2.1;r2=1.8.2.2.2.2) after 5 days it stuck again with same symptoms, I've also got some in the nfs state: FreeBSD .. 8.0-RELEASE-p2 FreeBSD 8.0-RELEASE-p2 #0: Tue Mar 16 22:56:51 EET 2010 ..@..:/usr/obj/usr/src/sys/MYGEN amd64 When attaching the debugger for an rpccon process, It stuck in here #0 0x000000080124051c in stat () from /lib/libc.so.7 http://img705.imageshack.us/img705/741/10032219218.png Can I do the online debug of the kernel, or how can I can help you to solve the problem ?
