    Description

      We lost the ability to post transactions to the STN ledger.  Looking in the logs, a view change, cause unknown, occurred on all the nodes that I have access to at March 30, 02:42 GMT.  The last transaction posted to the ledger is timestamped 1522356428, which is March 29, 20:47. I have access to 7 of 10 nodes, and their logs are attached. 

      At 17:16 GMT I restarted the indy-node service on those nodes and saw that in the view change the original primary was restored, and I was again able to post transactions. 

      Please analyze the attached logs, and determine insofar as is possible:

      • What caused the view change?
      • Why were we unable to post transactions?
      • Following the restart, were all 10 of the nodes participating in consensus?
        • The nodes that did not restart are NewtonD, RFCU, and ibm

      Secondary questions:

      • Were there attempts to post transactions to the ledger before the view change that failed?
      • When did the fault state begin, where transactions were not posting?
      • Did the view change cause the lack of consensus, and why would it?
