This problem is relates with Alert definition:
Flow alert on all interfaces causes Reaper service to stop and will not start and create application error until the alert has cleared from the harvester.trap_definitions table.

 

NFA 9.5

Check on Harvester machine:
mysql
use harvester
select * from trap_definitions;

And on Console machine
mysql
use reporter
select * from trap_definitions;

Remove this Alert definition on NFA web page/Administration/Alerts Description "h interface" or use this command:

Check again on both NFA Console and Harverster machines:
select * from trap_definitions;

Note: You can force the remove with this command:
delete from trap_definitions where TrapName = 'nnnnn';  ---> Where nnnnn is the TrapName from select * from trap_definitions output
Run this command on Console and Harverster machines

Stop/Start the CA NFA Reaper Service
