Description

observation

When there are more than two browsers (say users) looking at a job's live view, the third one henceforth will take a noticeable time to load.

steps to reproduce

  1. Go to openqa.suse.de
  2. Go to All tests, and choose one running job, and open the live view
  3. Open again the live view for the same job 4 times

problem

Somehow the webUI is getting stalled trying to process the 3rd/4th request (Stalling on images mostly)

suggestion

Check the sub streaming lib/OpenQA/WebAPI/Controller/Running.pm

workaround

Have no more than two live views enabled.
