Hi,

I'm trying to pgAdmin4. I'm able to run pgAdmin4.py in python shell. And server runs.And able to access using browser.
Then I tried running desktop application, it throws following error,

Traceback (most recent call last):
  File "/home/prasad/Development/pgadmin4/web/pgAdmin4.py", line 73, in <module>
    app.run(port=server_port)
  File "/usr/lib/python2.7/dist-packages/flask/app.py", line 772, in run
    run_simple(host, port, self, **options)
  File "/usr/local/lib/python2.7/dist-packages/Werkzeug-0.10.1-py2.7.egg/werkzeug/serving.py", line 622, in run_simple
    reloader_type)
  File "/usr/local/lib/python2.7/dist-packages/Werkzeug-0.10.1-py2.7.egg/werkzeug/_reloader.py", line 263, in run_with_reloader
    signal.signal(signal.SIGTERM, lambda *args: sys.exit(0))
ValueError: signal only works in main thread
Initial connection failed. Retrying in 2 seconds.
Initial connection failed. Retrying in 3 seconds.
Initial connection failed. Retrying in 4 seconds.
Initial connection failed after multiple attempts. Aborting.


I can see what error says. As Qt application spawns separate thread to run server, which apparently is not allowed.
Am I missing something ?

regards,
Prasad
