My big NUMA box went OOM over the weekend and started killing things
for no good reason (2.5.43-mm2). Probably running some background
updatedb for locate thing, not doing any real work.

meminfo:

Looks like a plain dentry leak to me.  Very weird.

Did the machine recover and run normally?

Nope, kept OOMing and killing everything .
 

Was it possible to force the dcache to shrink? (a cat /dev/hda1
would do that nicely)

Well, I didn't try that, but even looking at man pages got oom killed,
so I guess not ... were you looking at the cat /dev/hda1 to fill pagecache
or something? I have 16Gb of highmem (pretty much all ununsed) so 
presumably that'd fill the highmem first (pagecache?)

Is it reproducible?

Will try again. Presumably "find /" should do it? ;-)
