Hi, I've setup that 0.7.0-dev server yesterday, and I'm now fooling around with the parallel backend instead of multi. When [EDIT]~~bui-manage~~ bui-monitor [/EDIT] service isn't enabled, bui-gunicorn fails as follows: ``` During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/local/lib/python3.6/site-packages/gunicorn/arbiter.py", line 583, in spawn_worker worker.init_process() File "/usr/local/lib/python3.6/site-packages/gunicorn/workers/base.py", line 129, in init_process self.load_wsgi() File "/usr/local/lib/python3.6/site-packages/gunicorn/workers/base.py", line 138, in load_wsgi self.wsgi = self.app.wsgi() File "/usr/local/lib/python3.6/site-packages/gunicorn/app/base.py", line 67, in wsgi self.callable = self.load() File "/usr/local/lib/python3.6/site-packages/gunicorn/app/wsgiapp.py", line 52, in load return self.load_wsgiapp() File "/usr/local/lib/python3.6/site-packages/gunicorn/app/wsgiapp.py", line 41, in load_wsgiapp return util.import_app(self.app_uri) File "/usr/local/lib/python3.6/site-packages/gunicorn/util.py", line 362, in import_app app = eval(obj, vars(mod)) File "<string>", line 1, in <module> File "/usr/local/lib/python3.6/site-packages/burpui/app.py", line 118, in create_app app.setup(app.config['CFG'], unittest, cli) File "/usr/local/lib/python3.6/site-packages/burpui/engines/server.py", line 398, in setup self.load_modules() File "/usr/local/lib/python3.6/site-packages/burpui/engines/server.py", line 488, in load_modules raise exc File "/usr/local/lib/python3.6/site-packages/burpui/engines/server.py", line 477, in load_modules self.client = mod.Burp(self, conf=self.conf) File "/usr/local/lib/python3.6/site-packages/burpui/misc/backend/parallel.py", line 242, in __init__ raise exc File "/usr/local/lib/python3.6/site-packages/burpui/misc/backend/parallel.py", line 233, in __init__ trio.run(connector.conn) File "/usr/local/lib/python3.6/site-packages/trio/_core/_run.py", line 1444, in run raise runner.main_task_outcome.error File "/usr/local/lib/python3.6/site-packages/burpui/misc/backend/parallel.py", line 76, in conn raise BUIserverException(str(exc)) burpui.exceptions.BUIserverException: all attempts to connect to 127.0.0.1:11111 failed ``` Maybe gunicorn shoudn't be killed when bui-monitor does not work. Also, `bui-manage diag` will fail with `Unable to initialize the application 'diag': Failed loading backend burpui.misc.backend.parallel:` if bui-monitor isn't working (in my case, I had to specifiy an alternative burpbin path). I think the diag should work regardless of bui-monitor working. Also, I think I found a small problem: When timeout is commented out in bui-monitor.cfg, there's no default value of 15: ``` [2019-08-19 12:24:28,722] INFO in config.safe_get: the value "None" is of the wrong type. [Burp]:timeout - found: None, default: 0 -> 0 ``` Anyway, didn't get parallel workingb today, I have alot of those timeout I'm still trying to find the reason of. ``` [root@burp burp]# /usr/local/bin/bui-monitor -c /etc/burp/bui-monitor.cfg -vvv [2019-08-19 12:33:48,968] INFO in monitor.__init__: conf: /etc/burp/bui-monitor.cfg [2019-08-19 12:33:48,968] INFO in monitor.__init__: level: INFO [2019-08-19 12:33:48,969] INFO in config.safe_get: the value "None" is of the wrong type.
