#hqueue

Recently, a situation arose where each client was properly functioning, and could see the HQ server. Each machine could also run Houdini independently, both as the normal user and the hq client user. 

However, when I submitted jobs to those machines via HQ, they would all throw an error: No licenses could be found to run this application.

After quite some time digging around and troubleshooting, the solution turned out to be pretty simple: restart hserver:

Double-check the correct license server is running with hserver -l

Kill the hserver with hserver -q

Run the hserver with hserver

For some reason, hserver still has something still pointing to the wrong license server somewhere, but that was only being found when HQ fired up the jobs. Restarting hserver did the trick!
