Can you show the output of

Code: Select all

service ndo2db start
service ndo2db status

Posted: **Mon Nov 04, 2019 2:13 pm**

Starting ndo2db (via systemctl): [ OK ]
[root@gaatlp82u var]# service ndo2db status
ndo2db is not running

Posted: **Mon Nov 04, 2019 3:34 pm**

Lets run the following

Code: Select all

rm -rf /usr/local/nagios/var/ndo2db.lock /usr/local/nagios/var/ndo.sock
service ndo2db start
service ndo2db status

If you still get

Code: Select all

ndo2db is not running

send the result of the following:

Code: Select all

grep ndo2db /var/log/messages|tail -20
