Since more than five weeks the Dom0 is running stable with the Debian 9 distributed Xen version 4.8.3+xsa267+shim4.10.1+xsa267-1+deb9u9 while with version 4.8.4+xsa273+shim4.10.1+xsa273-1+deb9u10 it was crashing between once every two weeks and twice a day.
We have several other servers with similar hardware and kept on the 4.8.3 Xen version, which never crashed so far. Another server, that was crashing with Xen 4.8.4, is running it with "pcid=0" since 31 days. However we migrated several machines away from that one, so that it has a very low load/diversity within the set of guest, which might falsify results. I hope this helps a bit to find the cause of the crashes. If you need any further information, please let me know!
