I export a few samba shares from a FreeBSD amd64 server and I've been

This /usually/ works fine, but occasionally I'll get a pause of several
seconds when I save back a modified file.  No errors are generated on the
server, but it causes the smbd process takes a few % of available cpu time,
according to top.

Could this be due to the infamous seekdir/seekdir issue between samba and
FreeBSD?  Some of the directories do contain hundreds of files.  This post
suggests it has been fixed though: http://www.vnode.ch/fixing_seekdir

The server is running -STABLE ('FREEBSD 7.1-PRERELEASE'), as built on
2008/09/08.  The file system is zfs.  I'm using samba 3.0.34,1, built from
ports.
If you can reproduce this behavior using local access or ssh access (taking samba out of the equivalent) I would take it over to freebsd-fs.
The seekdir is indeed fixed.
If not, increase verbosity for smbd, maybe it spits out a hint why it is taking so long (smells like locking).

I just moved my work to an exported UFS partition and I've seen the same problem appear a couple of times. It's possibly a little less frequent though.

So with zfs off the hook, it's possible that the problem lies with samba (or maybe the editor itself, although I don't remember ever coming across the issue before).

Cheers,
