ver 6.7 error 503 Service Unavailable (Failed to connect to ...websso action = Allow _port= 7080

[arcolino1]

hello, third time getting this error " 503 Service Unavailable (Failed to connect to endpoint: [N7V******] _serverNamespace = /websso action = Allow _port = 7080)" I searched around found various possibilities but non worked, rebooting the appliance from a ssh session fixes it, I checked events did not find any errors in there, where I can find the place to look by command line or the gui on what is causing this and the fix for it?

Check  if any partitions are filling  up. Run df -h 

Also run  service-control --status --all to check if any   critical service goes down.

Also go under /var/core and   check for any recent core/dumps.
