I noticed Vincent committed a few memory leak / xenstore fixes today. I immediately pulled that down and am seeing how well things run now. Users also reported receiving BUG's in their domains, I submitted a bug regarding this. I have set vcpus=1 for every domU now just in case SMP inside the domU was affecting Xen / dom0 Linux. I will update if this solves my problems or if they change / persist. Thank you to the Xen developers for assisting me with diagnosing these odd problems that only those of us brave enough to try -unstable in production can probably find :) Cheers! Matt Ayres
