Hi Adnan,
Please try restarting the following processes during non-production hours & see if it fixes the issue.
(Aruba) #process restart httpd
WARNING: Do you really want to restart process: httpd (y/n): y
Restarting: httpd
(Aruba) #process restart arci-cli-helper
WARNING: Do you really want to restart process: arci-cli-helper (y/n): y
Restarting: arci-cli-helper
It will take couple of minutes for the process to restart. We can monitor the same using the following command:
show process monitor statisitics | include httpd
show process monitor statistics | include arci-cli-helper
When both the process shows up in running state post the restart, please veirfy the status on the Web UI.
