Cbc resolution time

[Azi2021]

Hello everyone,
I am solving an MIP problem with AMPL+CBC. I have set the time limit to 1h and recorded the CBC log (attached to this message). Apparently, only two nodes were searched, and it's not clear what else CBC was doing that took so much time. Now, my question is why Cbc has not stopped the search and how can I adjust relevant options to stop CBC as soon as it has found the optimal solution?
I also attached a second log file for a recent test that I set slog=0 to avoid less important info.

Thank you in advance,
Best regards,
