5.3-S (Mar 6) softdep stack backtrace from getdirtybuf()... problem?
I have twice so far had the kernel syslog a stack backtrace with no
other information. Inspection of the kernel source, to the best of my
limited understanding, suggests that getdirtybuf() was handed a buffer
without an associated vnode. Kernel config file and make.conf attached.
Should I be concerned?
Note that this system is an older 600MHz Athlon with only 256MB RAM, and
both times this triggered it was thrashing quite a bit (that's more or
less its usual state...).

I never did hear of a definitive resolution for this issue; your backtrace is alarmingly similar to the one that I had seen. http://lists.freebsd.org/pipermail/freebsd-current/2004-July/031576.html Sven

I suspect this is a issue with busy NFS server? rafan.
