Bluemix IoT Foundation Starter give Error: Lost connection to server -


i trying internet of things foundation starter boilerplate in bluemix. here steps following:

  1. create new app using boilerplate
  2. once app up, go url , see nodered home page
  3. i click on button take me nodered editor
  4. in browser window have iot sensor available here: https://quickstart.internetofthings.ibmcloud.com/iotsensor/ , running
  5. i configure "iot app in node" address of iot sensor. have removed ":"'s , have made letters lowercase.
    1. when click deploy in nodered editor, see following error: "error: lost connection server"

after step 2 see these errors in log:

after step 5 after error happens, see following error:

now if restart app works fine. can recreate above scenario consistently every time these steps:

  1. create new app boilerplate
  2. go nodered editor
  3. configure iot in-node
  4. deploy
  5. get error
  6. stop , start runtime
  7. all works

need figuring out why happening , how prevent it.

thanks

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
