Data Services Job server starts job multiple times

Dear all,

we are experiencing a very weird issue:

We are on DS 4.2 SP10

Jobs are scheduled with the Data Service Scheduler

Sometimes (can be different jobs) the jobs start multiple times (2 times or more; sometimes within seconds, sometimes within minutes) it does not happen every day and in the Task Scheduler there is only one task per schedule.

The jobs sometimes fail or are successful. Problem is if a job is successful and ran 3 times we get tripled lines which is causing a huge issue.

Here is a screenshot of a job that ran tiwce times.

Have any one of you experienced something similar?

Would really appreciate some help as this is causing a lot of pain

Kind Regards

Chris
