Console log from hyperion-agb20 (dead OSS)

System had started iorfpp, node had repeated watchdogs after the LBUG.

[Peter Jones]

Oleg what do you suggest?

[Oleg Drokin]

Cliff did a rerun of the test and it did not reproduce.

The error message itself does not make much sense, and we do not have any extra debugging info, so I do not hink we can do anything about this. Could be a one-time fluke too.

Cliff has rerun tests and unable to reproduce this issue.
