In receiver we are getting too many error message "Process hactl is not running"
whether anything critical need to be checked on the receiver end ?
why we are getting error message in the receiver ?
If I'm not mistaken, that is a process that control HA mode on receivers. Is this an HA setup?
If so, You might want to try stopping/starting services on the affected receiver(s) and or rebooting them.
Please check the ERCs nodes status (ERC Properties page) - should be OK. If not for the one of the ERC, try to use NitroStart or Return to Service function.
