While the out of memory improvements from yesterday have helped, the erratic block times have returned. We believe this has to do with the gossip network topolology degrading over time (an OTA resets the gossip network connections as the nodes reboot). We have identified some more fixes that should help block propogation times between the consensus group which should limit the impact of bad gossip topologies on the block production rate.
- Cleanup Proof of Coverage state machine: PR: miner/277
- Fix some deadlocks in blockchain core: PR: core/357
- Fastforward consensus members that did not sign the block and gossip full block signature list: PR: miner/300
We'll beta this release briefly starting around 4pm PST and release it to general availability this afternoon or evening.
