No, softupdates is not enabled on this filesystem. Other filesystems
on the same machine that are used lightly and are not full do have
softupdates enabled though. (we have v1.21.2.3 of ffs_balloc.c anyway)
The panics have been occurring every few days recently, and their timing
always corresponds within a few minutes to the filesystem becoming full
(/var/log/messages will have a flurry of 'file system full' messages
just before the reboot).
An example trace is below. Let me know if any further information would
be useful.
