Closing in favor of #3092 which fixes the root cause. The timeout widening only masks the symptom. The actual issue is that `selectQueue` in `Association.send` uses the anchor's UID (root guardian, always 0) as the distribution key for outbound lanes. With `outbound-lanes > 1`, all ActorSelection messages concentrate on a single lane (`math.abs(0 % N) = 0`), creating a throughput bottleneck. #3092 distributes ActorSelection messages across lanes based on their target path hash instead, eliminating the structural bottleneck. -- This is an automated message from the Apache Git Service.
