@marcoi I don't have enough context to reply. You should open a new thread to discuss it, with details about your needs (always better to explain the needs before the technical solution).
Apologies for the late response - life got in the way!
I tried your tweaks and these appear to have solved the issue. The VM has been stable for over a month, which also included a reboot or two to install updates. Thanks for the help.
I am seeing this error on all VMs on a host.

I have checked the Xen Tools and the latest version is installed.
