I didn't have BREAK_TO_DEBUGGER = enabled in the kernel so I couldn't get into the debugger. I fixed that = so hopefully I can get that next time. I haven't seen any vr errors (thanks for telling me how to). Indeed as = someone else pointed out, it's likely not related to 'vr' at all. When = it last hung the 'top' execution stopped about 15 minutes before the box = stopped routing packets; but during the last runs the interrupt "busy %" = according to top was only 30-ish percent. I didn't log the interrupt rate when it was crashing; but the ifconfig = and dmesg outputs didn't show anything. (Though my logging jobs might = have stopped well before the system failed, similar to the shell running = top). Grasping at straws here, but when enabling BREAK_TO_DEBUGGER I noticed = that the kernel had ZERO_COPY_SOCKETS and TCP_SIGNATURE enabled. I = disabled those, "just in case". - ask --Apple-Mail=_6413ECB9-93A9-41EC-9BEC-95B1379028E3--
