             Summary: DUCC check_ducc -k should not use -9 to kill the 
database, by default
                 Key: UIMA-5418
                 URL: https://issues.apache.org/jira/browse/UIMA-5418
             Project: UIMA
          Issue Type: Bug
          Components: DUCC
            Reporter: Lou DeGenaro
            Assignee: Lou DeGenaro
             Fix For: 2.2.1


Normally, check_ducc -k sends -9 signal to those process it aims to kill, 
including the database.  This may leave the database in a bad (unusable?) state.

1. Change check_ducc -k to issue signal -9 to all daemons except database which 
will get -3.

2. Change check_ducc to accept the --db-9 option that indicates that the 
database should get signal -9.  The db-9 option only applies if the -k option 
is also specified, and should be used only as a last resort.
