Also, groupstats show that peak active probes count was 133.
The shape of the cwnd curves kind of looks like response rate scaling isn't working properly. It looks like a square root rather than a line. It could happen if num_replies_expected isn't increased properly. Or it could be because cc_scale reached cc_scale_max.
