Subject: [uml-devel] UML not returning memory
Date: Mon, 11 Oct 2004 21:04:39 -0400 [thread overview]

Host:
gimli-[aggr/testing/pluto/basic-pluto-01] mcr 1097 %uname -a
Linux gimli 2.4.24 #4 Tue Mar 9 22:18:59 EST 2004 i686 GNU/Linux
debian-sarge, linus kernel.
I seem to be running in TT mode, rather than MM.
(I guess I forgot to apply skas3 on this host)

As I run, I gradually run out of memory.
I start UMLs and stop them, reboot them, lots as I am working.
The box does nothing else. I killed all random processes that might have
been using ram, but the memory does not return. We had this problem
on another box, and never figured it out.
I expect that UML is allocating memory and never returning it.
But, given lack of /proc/mm, I don't see how it could be doing this kind
of thing.
Any ideas of where else memory might be disappearing to?
