In order to make sure I can do the best job here, can you please provide your specific expectations and how did they fail?

Also, a specific version of the bridge used will be helpful to have.

[rstormsf]

1 updated bridge node successfully processed it.

2 other old May 10th bridge rust node missed it.

[yrashk]

Ok, so you expected old bridge to work, but it didn't. You also expected the new bridge to work, and it did. Correct?

[rstormsf]

Looking more into it,
looks like it is problem with new bridge rust node

[yrashk]

Please specify what seems to be the problem, as precisely as reasonably possible.

[rstormsf]

CollectedSignatures event was fired and the node that was responsible for it - send a tx to Home bridge which failed

Problem was resolved. Relaying the analysis by @rstormsf: default gas limit for withdraw_relay was set to 100k in the configuration, updating it to 300k resolved the issue.

[rstormsf]

yes, also if the bridge was using estimateGas without relying on those hard coded values, we wouldn't have this issue as well
