I don't think it explicitly stops after the first occurrence but it
seems to have limited ability to dig around. Simplifying, it only digs
around for 5-10min, and it spends a lot of time proving that the
issue is real. So once it's spend time proving one issue it's often out
of time, and may not search for another one :(

Ccing Chris, hopefully he'll chime in later if I'm wrong.
