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
