Xen users - Jan 2006 - Memmory "leak" using 32bit userspace with 64bit Xen kernel

Dear list,

more fun with my Athlon64 X2, running Xen3.0.0-64bit (binaries from
xensource) when using the provided DomU kernel to run 32bit userspace
(debian sarge 3.1).

Something on my 32bit DomUs keeps on allocating about 8byte/sec of 
committed memmory. After less than 5 days this results in 1.8GB of
committed_as memmory. This is not used memory, just allocated, so this
is not realy a problem but the memory-usage graphes look kind of broken.

I can kill all userspace processes, but init and the bash I''m using
and the memmory is still allocated.

This does not happen when using 64bit userspace (debian sarge, too).

- has anyone seen this, too
- has anyone an idea how i might fix this?

Thanks a lot,
    Goetz.

Does this happen when running a 32bit env without Xen ?

I''ve seen this for ages with Sarge. Without Xen.
