Unexpected log output - appears to double sign #314
Description
We're testing an active/active setup of two validators connecting to a single tmkms v0.6.0-rc1 process on the gaia-13004 testnet.
AFAICS in the source, "signed at height" is only logged after a signature is created:https://github.com/tendermint/kms/blob/e5dadf1a7bef351ea78c082e1aefab3db44aedfc/src/session.rs#L221
So it appears tmkms is double signing for the same chain id?

Our validator is not getting slashed so far.. Maybe because we have yet to propose a block and have been lucky so far (prevoting/commiting on same data on both vals).
