Troubleshooting Tip: FortiGate GUI becomes unresponsive when filter is applied to the logs
| Description | This article describes the issue where the FortiGate GUI becomes unresponsive or gets stuck after applying filters in the Forward Logs following an upgrade to firmware v7.6.6. |
| Scope | FortiGate. |
| Solution | After upgrading the FortiGate to FortiOS v7.6.6, the GUI may enter a hung or unresponsive state when applying filters on logs. The issue can also be observed from the CLI using the following command:
diagnose sys top
01:44:14 PM up 4 days, 16 hours and 15 minutes 3U, 0N, 27S, 69I, 0WA, 0HI, 1SI, 0ST; 1933T, 714F httpsd 13039 D 58.4 2.5 2 ---> (D= Disk sleep) httpsd 13025 R 57.0 2.0 2 forticron 153 S 2.7 1.5 2 miglogd 240 S 0.5 1.6 2 node 164 S 0.3 3.1 3
This indicates that the GUI-related service is stuck while processing the log filter request.
As a workaround, disable application resolution in the GUI log display settings using the following CLI commands: config log gui-display set resolve-apps disable end 
This issue is currently under investigation, and it is expected to be fixed in v7.6.7. |
