Thank you Todd.  It seems strange though that this is only happening on one
node and has never occurred on any others that are using the same JVM
version.  This node was just auto-bootstrapped so do you think this might be
the result of some sort of data corruption?  I would like to just
decommission it but I'm not sure that that would fix the corrupted data (if
it is actually corrupted).  Do you know if compact or repair would detect
bad data and disregard it?  I'd like to try something like that if possible
before just upgrading the JVM and potentially hiding the real problem.
