The data is with the outputs in the "info" file, not in the DB :(
I hacked up a bash script to fetch those:

Looks like for the failed cases local_termination.sh always runs 
before router-bridge, and whatever runs next flakes:

Thread4-VM0
	 5-local-termination-sh/
	 20-router-bridge-lag-sh/
	 20-router-bridge-lag-sh-retry/

Thread4-VM0
	 5-local-termination-sh/
	 16-router-bridge-1d-lag-sh/
	 16-router-bridge-1d-lag-sh-retry/
