11/3 Network Update Issue #551-nodes may get stale at a block

11/3 Network Update Issue #551

We are facing a very serious problem with the v0.9.12 substrate upgrade we had 2 days ago. All the nodes in the network may operate normally for around one day and then get stale at a block.

#Tracking issue
Khala v0.1.7 node got occasionally full network stale · Issue #551 · Phala-Network/phala-blockchain · GitHub

We are addressing this issue with Parity. Before we have figured out the solution, a walkaround is to reboot the node every time when it got stuck.
