hi all,
we are having an "issue" with some SL61 nodes. after a reboot, free
reports 1.4GB of memory in use, of which 24+163=187MB buffers+cache.
i'm unable to identify what is holding the memory, and i'd like to know
if others see this too and how i could proceed to find the culprit.
(it is a 32core/64GB machine; kernel commandline has
crashkernel=128M@16M (but no difference then eg crashkernel=auto and
kdump is off))
many thanks,
stijn
