I have recently began mounting /usr/ports as nullfs and unionfs on top of it, and I believe this causes the system crashes during the intense file activity on the unionfs-ed /usr/ports. /usr/ports.patches on /usr/ports (nullfs, local, read-only) :/usr/ports.subversion on /usr/ports (unionfs, local, noatime) The messages I reported are related to this.
