[Xen-users] domU die by hand of oom-killer

[chrysn <chrysn@xxxxxxxx>]

hello,

as per suggestion from irc, i post this here:

i have a debian etch dom0 with 3gb ram, plenty of swap space, and xen
running.
i used to have a mixed setup of modified and unmodified linux domU, but
i changed to running all unmodified when the last 2gb of my current 3gb
ram arrived.

two days after changing to the pae-build of xen and un-modifying the
guests (something broke in the transition; unmodified guests are easier
to maintain), single domU started to freeze; it turned out that the
out-of-memory killer killed qemu-dm or its python parent (both happened).

the dom0 has 391mb of ram at its disposition and an additional 1gb swap
space. top says none of the processes is using more than 1.5% memory
under normal observation.

any ideas on what makes those processes eat up much more memory (at
least i guess they do, unless the oom killer went rogue) and how to
prevent it?

logs are attached
xen version is "3.0.3-1 (Debian 3.0.3-0-2)"
