I'm seeing the same issue. We have one SSIS package that we call with different parameters for different client data.

I'm attempting to have the SQL Jobs kick off at the exact same time and process the data in parallel but am getting these exact same deadlocks. Ideally I'd like all the SQL Jobs to reference the same schedule so that I can edit one schedule and adjust all the SQL jobs at once. Spacing out the jobs would negate that.

Is this just a limitation of SSIS and the catalog?
