Based on investigation , bifrost signed & broadcast the transaction to ETH , but unfortunately it failed to commit to block , because of running out of gas

This is a bug in !1986 (merged). The PR was mean to remove the transaction that failed due to running out of gas from bifrost's internal signer cache, but it fail to do so. The bug is in ETH block scanner , it didn't remove the signer cache
