My 11.0-STABLE system had been working stable for a three last years, but became unstable a week ago. The system just freezes about once/2 days (at night) and no responsive via network, nothing in the console. Before the first freezing I had made updates of applications in the base system and jails. Options VIMAGE and Linux compat. are enabled. The first thought was bad sectors on the HDD, but  dd if=/dev/ada0 of=/dev/null bs=128k rejected this one. How can I debug this situation? Thank, Vit
