   - click one dashboard with 5 charts, the page loads successfully, however, when i click "Force Refresh" , 
   return **502 bad gateway**, the sever went down and restart.   
   we tested refresh 2 charts at the same time , it also loaded successfully. when refreshing more than 3 charts ,the program went down and retart. 
   
   in the config.py :   SUPERSET_WORKERS = 2
   
   anyone can give a hint for debug?
