Old host status info on web interface seems like a bug

I did try setting retain_status_information to 0 for the hosts in
question.  I then reloaded nagios and then set it back to 1.  After
reloading the status went to red and the old status error appeared
again, until once again
check_dummy was performed and it switched to OK/green.  Basically, even
setting retain_status_information to 0 for a while doesn't flush out the
old error status. retain_state_information is set to 1 in nagios.cfg and
retention_update_interval=60.  I will try removing the
state_retention_file next.  Thanks for your help!
