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: # -- Add Support for nicer console # options VESA options SC_PIXEL_MODE # -- IPFW support # options IPFIREWALL options IPFIREWALL_VERBOSE options IPFIREWALL_VERBOSE_LIMIT=10 options IPDIVERT options IPFIREWALL_FORWARD
