This was a one time event, and I don't know of a way to replicate it at
this time.  Monitors of the box showed it was largely idle at the time
the bug exhibited itself.  VMware reported repeated high/low CPU
consumption from the time of the bug until it was forced off and
restarted.  The host WAS responding to pings,  but was unable to be
logged into and monitors of the host stopped at the time of the syslog
message of the bug assertion.  cacti graphs stopped capturing data at
the time of the hang

Prior to the hang, cacti graphs showed a fair bit of Disk IO (for this
VM), about 543 sectors/second read, and 1300 sectors/second write, where
daily averages are 15 read and 44 write sectors/second respectively.
