> +Question:+
> I cant start context broker due to "error starting REST interface"
> +Description:+
> When I enter the following command:
> /etc/init.d/contextBroker start
> I get the following output:
> Starting contextBroker...                         cat: /var/run/contextBroker/contextBroker.pid: No such file or directory
> pidfile not found                                          [FAILED]
> I have two machines where I am practising with context broker and I havent touched the second one in days after I succesfully installed it and managed to receive a post message from a remote weather station.
> I see that the directory /var/run/contextBroker/ is actually empty
> What should I do to fix this now? reinstal context broker or?
> So is this somehow my fault and how do I prevent in the future? I dont want this happening when my app goes live.
> EDIT1: the orion version is 0.20.0
> EDIT2: I just reinstalled contextBroker and I get the same problem. What are exectly the contents of that directory? Could I maybe just create the files inside?
> EDIT3: Since running contextBroker as a system service still yields an unsuccessful start, I also attempted to run it symply by typing:
> contextBroker in the command line, after which I get the following response
> INFO at 14:03:03  contextBroker.cpp[1346]: Orion Context Broker is running
> [root at localhost DevF12]# INFO at 14:03:03  MongoGlobal.cpp[181]: Successful connection to database
> INFO at 14:03:03  contextBroker.cpp[1157]: Connected to mongo at localhost:orion
> INFO at 14:03:03  MongoGlobal.cpp[499]: Database Operation Successful ({ conditions.type: "ONTIMEINTERVAL" })
> FATAL at 14:03:03  rest.cpp[1013]: Fatal Error (error starting REST interface)
> EDIT4: Ok so I tried ps aux | grep contextBroker and the result is:
> 494       2196  0.0  7.0 688696 135116 ?       Ssl  Apr21   0:02 /usr/bin/contextBroker -port 1026 -logDir /var/log/contextBroker -pidpath /var/run/contextBroker/contextBroker.pid -dbhost localhost -db orion
> root      7299  0.0  6.9 621052 134440 ?       Ssl  04:21   0:00 contextBroker -port 1028
> root      8870  0.0  0.0 103256   848 pts/0    S+   08:51   0:00 grep contextBroker
> but there simply isnt anything in /var/run/contextBroker/
> Should I put contextBroker.pid by myself? and if so, what should the contents be?
> EDIT5: I just ran netstat -ntlpd | grep 1026 and the output is:
> tcp        0      0 0.0.0.0:1026                0.0.0.0:*                   LISTEN      2196/contextBroker  
> tcp        0      0 :::1026                     :::*                        LISTEN      2196/contextBroker 
> So I guess nothing else but contextBroker is listening?
