Could this cause the above?
Caveat: this may be a "red herring." But please note that for stable/7 prior to r190970 (2009-04-12 10:43:41 -0700) or head prior to r189287 (2009-03-02 12:51:39 -0800; prior to stable/8 branch, so it's part of stable/8 already), there was a rather nasty (IMO, as I spent a fair amount of time trying to figure out what was going on) such that a FreeBSD NFS client would see precisely the above symptoms if: * A process on the FreEBSD NFS client performed a chdir() to a directory that was NFS-mounted, then started a "recursive descent" (e.g., "tar c ..." or "rm -fr") from that directory and * Some other process on the same FreeBSD NFS client attempted to perform an unmount() of the NFS-mounted file system referenced above. Note that the unmount() is doomed, as the file system is active -- a directory in it is the $cwd for the first process, after all. This may seem an unlikely -- possibly even perverse -- combination of events. However, it is actually SOP for amd(8): the master amd process periodically forks a child to perform an attempted unmount of auto-mounted NFS file systems periodically, and the way amd realizes that the file system is not eligible for unmounting is if the attempted unmount() gets EBUSY. It is *possible* that something akin to this mechanism *might* be affecting the OP. Peace, david -- David H.
