FAQ
ParticipantAnswer: By way of explanation, a static port address is used for our monitor ring code (i.e process cleanup code in the event of failures) during start up. If the address used by the monitor ring code is already in use by some other application this error is encountered. As a workaround please use the following flag when launching Fluent: -nmon By using this flag we are disabling the monitor ring code, so this issue is not encountered. By using this flag, in the event of a Fluent failure, automatic cleanup will be disabled. So, in the event of failures, you will need to manually run the Fluent cleanup script for cleaning any orphan processes. In the Fluent Launcher, Environment Tab, please put in the following variable: FLUENT_SKIP_MONITOR_RING=1
