Lou DeGenaro commented on UIMA-5138:
------------------------------------

In the event of disk write error the DB is configured to suspend processing of 
requests, but the DB process remains up.  The WS detects that DB is down in 
this situation.  

With new functionality, the WS adds disk usage information comprising 
filesystem and quota usage to the DB down alert banner.  This additional 
information is gathered at the time of DB down detection and remains as such 
until the DB and/or WS is restarted.
