Since upgrading the ports cluster to 4.5 I've been seeing a lot of UFS
panics (about one a day, over the 8 client machines). I upgraded the
kernels yesterday to try and fix this, but one of them panicked again
today. I managed to capture one of the panics, and I have the core.
Is there anything else I can provide?
