I had a similar problem between processes a few months ago,
I also posted an example, unfortunately with no resolution
nor further inquiries from the developers. I suspect the skas3
patch does not get much attention now...
Try to run the guest with mode=skas0 - in my case it eliminated
the problem and the guest is running for months without a hiccup.
If your problem is the same, it will probably help as well.

In my case it was reproducible with 2.6.23.17 as well.
