Host/Worker appears to be offline in GUI but is not

[jesse]

In the Host/Worker tab one of my render nodes is marked as offline, but the service is still running on the node and the worker is still picking up and successfully completing sub jobs.
I've restarted the node entirely, and restarted the supervisor daemon.  I don't get why it is still marked as offline in the qube gui.
Any suggestions on further troubleshooting?

I just sorted it out.
I ended up doing this:

• stopping the service on the worker
• running: ./qbadmin worker --remove nodename007
• followed by: ./qbadmin worker --clearbanned
• then i restarted the worker service on the node

It seems to be back to normal.  Still, I could not figure out how it got in this state.
