Hi David, I checked and both instances of client have same parent process with pid 3933. I was doing load testing with large bursts of log messages (100MB in a minute) and then I noticed this behavior. Before using forcesingleinstance, rsyslog was spawning 4-5 instances of client to keep up with load.
