The nexus params chainMaintainerMissingVoteThreshold and chainMaintainerIncorrectVoteThreshold result in the side effect of de-registration of a large number of validators, as chain maintainers, for chains that see a temporary spike in transaction throughput.
The thresholds should be set to 100% while the core team develops a permanent solution, to prevent future outages of consensus based integrations caused by automatic de-registration.
A param change was tested on the testnet.
