What have you tried already? Jenkins re-ran the test and it passed the second time

Additional context N/A

The test code is not communicating with the Compactor. I think what I can do is have each test use a different compaction queue. Then, if a Compactor is running from a previous test for some reason, it won’t pick up the compaction. I’ll start on that change now. Is ExternalCompaction2_IT the only one currently failing?

I think this might be resolved with #2507. Are you still seeing issues with the ExternalCompaction ITs?

I think you are right. I haven’t seen it fail once since this change. My bet would be the distinct queue names did the trick. They seem to be very reliable now.
