Solution

EPAP having the alarm was Standby Server and Running in Release 16.1.1.

We found that we have had Syscheck error for mysqld process not running :

We checked the cgi.dbg logs and found getting DB_ERROR :

[root@mps-a logs]# tail -f cgi.dbg

04/10/18-11:01:48:<epapdev>:<mps-a>:<>::11366: Error 256 from mysql ping. Exiting repltest.

We tried to restart EPAP Services from CLI, but unable to start the EPAP services.

[root@mps-a logs]# service Epap stop
~~ /etc/init.d/Epap stop ~~
EPAP application stop Successful.
[root@mps-3001-a logs]# service Epap start
~~ /etc/init.d/Epap start ~~
setParam() failed with "DB_ERROR"
/usr/TKLC/epap/bin/uiEdit failed with return code 3. Is the UI database running?
[root@mps-a logs]#

We have had to reboot the EPAP A using "init 6" which bring back the server with all process running..
