Can you check based on last/daily mails/.. how many days it was since last reboot to a) see if it's close to a integer wrap-around or b) to give anyone who wants to reproduce this maybe a clue on how long they'll have to wait? For that matter, is it a stock 9.0 or your own kernel? What other modules are loaded?
Uptime was 31 days on the first incident / server (occurred 5 days ago)
Uptime was 4 days on the second incident / server (occurred last night)
One additional unique factor I just thought of: the two problem VMs have
4 cores allocated to them inside ESXi, while the rest have 2 cores.
Kernel config is a copy of GENERIC (amd64) with the following lines
added to the bottom. All the VMs use this same kernel which I compiled
once and then installed via NFS on the rest:
