I'm not aware of issues like this.

That's really strange.

I don't think so. Because first the .ubifs is generated, than it is compressed
by gzip -> ubifs.gz - If we have a space problem, the gzip should fail.

If so i would exepct that mkfs.ubifs or gzip produce those messsages and they
will end up in the elbe log file.

Hard to say what really happened. Is it possible to push the initvm + xml that
is able to reproduce the issue to some webspace for analyzation?
