If you can post a pipeline and small data set that reproduces the issue, I can take a look at it. Otherwise, you could reach out to support for additional help.

Thanks @tlikarish, I’ve already altered the pipeline and things are looking better. I had to avoid using the copy snap and aggregate or at least minimize the data set before it got to the aggregate.
