Replying to myself once more, mostly for the benefit of people

So, that helped, but it's not the entire story.
For anyone affected:
- Do you have ipmitool, libfreeipmi17, freeipmi-common installed?
- Are you running check_mk agent or another tool polling ipmitool
- Can you try uninstalling ipmitool libfreeipmi17 freeipmi-common
to see if the problem goes away?
Plus, if you happen to have check_mk and can't see details in your
memory allocation graphs, you can add an extra "slab only" graph
$opt = $defopt . "--title \"Slab only\"";
$def = ""
. mem_area("slab", "af91eb", "Slab (Various smaller caches)", FALSE)
starting at line 95.
