Colleagues,
I seem to have symptoms of kern/104406 on a 8.0-RELEASE-p2 system.
After an uptime of several days, many processes get stuck in the "ufs"
state. The processes which had already opened some files before the
deadlock continue working all right, e.g. my old login sessions are
functional but I cannot start a new ssh session to the box.
Can you advise me a workaround?
The box is being used as a BGP (quagga) router with two full views.
