FreeBSD Port: lsof-4.82A,3

  I have been using LSOF for a long time to determine if files are open
before processing.  I have seen since my newest
upgrade to 7.0 and 7.1 multiple instances of the core running the lsof
command pegging at or near 100%. Eventually
the whole system crashes. A report on the local console indicates it is
trying to reboot, however the server must be
hard booted to get past this point.

Has this already been reported? Either way please let me know what I can
provide to assist with a resolution on this.
So far I have not been able to replicate the error in a controlled fashion.

Thank you.

CLUSTER is a carp-enabled build, but is not currently configured in rc.conf.
Other than that it's generic.
