      Description

      Build tested: 1.4.4-1 (Jenkins 20200508)

      Test info:

      OS: centos7
      configuration: 3pm glusterfs

      When the stack is in a ready/normal state, I took of PM3 offline (vagrant halt -f PM3), failover completed. According to the debug.log on PM1, DMLProc got restarted after both "setSystemQueryReady" and "setSystemReady" have been set to 1. That took 4 to 5 seconds in my test system for system to be in ACTIVE state again.

      This could be an issue if the user or a script checks for "setSystemQueryReady" or "setSystemReady" to determine when to resume database operations.

      I waited for 15 minutes and there is no new entries to the debug.log file.
