      Description

      The following scenario was tested:

      • Determine Active NN and suspend the process (kill -19)
      • Wait about 60s to let the standby transition to active
      • Get the service state for nn1 and nn2 and make sure nn2 has transitioned to active.

      What was noticed that some times the call to get the service state of nn2 got a socket time out exception.
