As much of you know, a small percentage of Hotspots are having an issue with memory / sync issues and preventing them from participating in blockchain activity. The scale of the fix required for this issue is larger than the core developers expected and requiring them to rework the miner to use RocksDB’s checkpoint feature. This is a significant change and needs to be done safely.
There will be a separate release that is being testing tonight to support other efforts but it is not intended to address the memory issues. We should have an update tomorrow on the progress being made.
