----Security_Multipart(Wed_Jan__2_10_53_04_2013_899)-- Content-Type: Text/Plain; charset=us-ascii Content-Transfer-Encoding: 7bit Hello, I have been in a trouble about my NFS server for a long time. The symptom is that it stops working in one or two weeks after a boot. I could not track down the cause yet, but it is reproducible and only occurred under a very high I/O load. It did not panic, just stopped working---while it responded to ping, userland programs seemed not working. I could break it into DDB and get a kernel dump. The following URLs are a log of ps, trace, and etc.: http://people.allbsd.org/~hrs/FreeBSD/pool.log.20130102 http://people.allbsd.org/~hrs/FreeBSD/pool.dmesg.20130102 Does anyone see how to debug this? I guess this is due to a deadlock somewhere. I have suffered from this problem for almost two years. The above log is from stable/9 as of Dec 19, but this have persisted since 8.X. -- Hiroki ----Security_Multipart(Wed_Jan__2_10_53_04_2013_899)-- Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (FreeBSD) iEYEABECAAYFAlDjkwAACgkQTyzT2CeTzy19KACg3I02SLpt9/0k3oZf6CwwHZrC ghUAn0QDMU3L0vZ4QBbKU+vMa4QgV6qM =xeNb -----END PGP SIGNATURE----- ----Security_Multipart(Wed_Jan__2_10_53_04_2013_899)----
