@olivierlambert said: I'm not sure it's a great idea, because even 64 hosts is huge in terms of VMs and fallout if you have a problem on your pool DB. Even if you drastically improve the current mechanism, the impact of a problem pool wide is far bigger with 64 hosts than 24 for example. It's more than purely tech, it's also a tech design/choice. Exactly, the failure domain just grows exponentially when going beyond a certain collective pool size. I was doing some more research and I found a few possible choices that Tesco may have moved too, but don't want to detract from this forum here.

@Pilow pretty much

Here is the log from when xen04 last crashed xen04-jun12-journalctl-crash-summary.txt

@itservices Can you export your logs with xen-bugtool --yestoall please? If you prefer to avoid exporting everything, we especially need /var/log/xensource.log and /var/log/SMlog @Team-Storage do you have an idea about the source of the issue?

@AlexanderK you could try to install perl-interpreter manually maybe? I happened to have a test host at hand that hasn't been updated since december, and the yum update went fine, perl interpreter was not installed before and yum update did install it on its own as a depency for openssl 3. Maybe others will have ideas as to why this would happen in your case.

@tuxen Doing some research, it doesn't look like the Xeon's I have are affected. But I'm willing to try the next time I need to reboot. Will report back after that.
