Proxmox, the type 1 or “bare metal” hypervisor that we use, issued a kernel update this morning. There’s no security alert attached to it as far as I can see, and ours are pretty well locked down anyway, but sometime in the later evening U.S. west coast time I am going to restart this machine. Thirteen of the twenty virtual machines on this system are Open Semantic Search and they each require manual attention when restarted, so overall it takes about an hour to cycle the whole system.
Normal practice for something like this would be to schedule it for a low usage time period and just quietly do it. I’m making an announcement for the sake of those using OSS systems. If you see what behaving badly, or being completely out of reach, drop me a note about which one it is and I’ll coax it back to life.
