Troubleshooting Tip: High resource utilization and increased log verbosity after upgrading to version 7.6.5
| Description | This article describes a behavior that affects setups that are recently upgraded to firmware version 7.6.5. |
| Scope | FortiNAC v7.6.5. |
| Solution | When the setup is updated to this firmware version, the 'TelnetServer' debug will be automatically enabled after each reboot. This creates unnecessary load and produces extensive log output in the 'output.master' log file.
This can be checked by running the following command from FortiNAC CLI:
fnac76 # diagnose debug plugin list-debug-enabled
The debug can be disabled with the following command:
fnac76 # diagnose debug plugin disable TelnetServer
This procedure needs to be repeated each time the system reboots or the FortiNAC application is restarted. The engineering team is working to provide a fix for this behavior. For a workaround, contact TAC and mention engineering ticket ID 1246527. A definitive fix will be included in firmware version 7.6.7. |
