Hi Nyein,

I bet that you have two Windows task scheduler tasks running. Since your timestamps overlap, a second instance may be starting while the first one is still running.

You can check by looking on your web server, in Windows Task Scheduler, in the Dynamicweb folder. See if you have a duplicate job. If so, delete one of them.

Hi Scott, 

Noted with Thanks.  
Not every jobs happen like that but only few jobs runs twice and it happening not every day but on few days. 
May I know if there is also different reason for this case?

Thank you!

Best Regards,

Hi,
maybe you have the same Data integration job selected in the two scheduled tasks that run one after one?
Kind regards, Dmitrij

Hi Dmitrij,

This happens not on every day and we have also checked that same data integration is not selected on two scheduled tasks.  

Thanks & Regards,  
Nyein

Hi Nyein,

I don't know for sure, of course, but what you're mentioning sounds like 2 scheduled task runners. If you recently moved the site to another server, there may be an old one running on an old server. And that explains why it's intermittent too. It's a race condition where sometimes it hits the exact right time where the duplicate request doesn't get handled correctly, but other times it may be fast or slow enough to work correctly.
