Attached is the log for a set for 3 ingests. The first hump is with 1 ingestor, the second hump is with 2 ingestors, and the third hump is with 3 ingestors. The 3 ingestor case starts oscillating about 21:40. I don't see any spikes in any of the fields. It would be nice if there was also a plot of Xceivers since I think that anti-correlates. I do sometimes see the hold times highlighted in red. The values are usually in hundreds of msec.
