Hi Jimmy,


Could query timeout issue causes this problem and this error message? If im not mistaken the mysql setting has query timeout of 10 minutes. 


In the desktop I disable the enable parallel loading of tables option. So it query one by one, but in the service I dont think it is able to do that, so the query may take longer.


Thank you
