Greetings, I am experiencing a bit of a problem here on daphne, out of nowhere. The FRED services have never stopped running for two months now but daphne puts out the following message after hitting login. Error: Error: Backend server is not running! Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/fred_webadmin/exposed.py", line 25, in _wrapper return view_func(*args, **kwd) File "/usr/lib/python2.7/dist- packages/fred_webadmin/controller/adif.py", line 241, in login self._authenticate(form, admin) File "/usr/lib/python2.7/dist- packages/fred_webadmin/controller/adif.py", line 175, in _authenticate auth.authenticate_user(admin, login, password) File "/usr/lib/python2.7/dist- packages/fred_webadmin/auth/corba_auth.py", line 11, in authenticate_user admin.authenticateUser(recoder.u2c(username), recoder.u2c(password)) File "/tmp/tmprSxSnq", line 6903, in authenticateUser TRANSIENT: CORBA.TRANSIENT(omniORB.TRANSIENT_ConnectFailed, CORBA.COMPLETED_NO) All FRED services are still running. The logs don’t show anything conclusive, what could be happening?

OK, in any case I'd suggest to restart both backend service (fred- adifd) and also frontend service (fred-webadmin). If this doesn't help we will need to investigate what is preventing the communication of these two services. Is it running on single server or different servers? Regards, Jaromir

I had to wait to wait till off peak to restart the services, just to be safe. It seems that’s all it needed, the error is cleared and daphne works fine now. I wonder what could've caused the communication cut between the adifd and webadmin services.

If the backend server was refusing to run at all, could it have something to do with CORBA technology? I have that problem with fred-adifd service on a test server I made recently. Restarting does't seem to do the trick, it just can't start while other FRED services are running.

This is hard to say. The communication mediated through CORBA technology is quite complex and the glitch could be in many components. Maybe you hit some bug in this particular service triggered by high uptime. You may try to read logs for fred-adifd if you will see something from last time this service responded to CORBA calls.
