Description

I was observing status pages of testbed hubs and saw that number of PIT entries (+NameTree entries) is excessively high, given that there is basically no traffic. The behavior is kind of consistent across hubs (spurs and arizona has > 20k entries).

I suspect that something is not right with PIT expiration and the issue needs to be investigated.
