Hi All,

Does anyone have a clue about this issue?

Reported it before but there's been no resolution.

    Hi,

     

    The process tries to connect to a RM server and it fails. Can you provide more details on what you do? Is a parallel loop involved?

    Hi Martin,

    The process is saved in RM Server. There is no parallel loop. The error randomly occurs and usually I wait for about 8-10mins to try running the process again after which it runs smoothly. 

     

    Regards

    Hi @data123,

     

    Is this process running on a JobAgent? How is it executed (i.e. triggered manually or cron scheduled)?

    Do you have information regarding the Server load the times the error occurs?

     

    Happy Mining,
