Description
This article explains an issue where the browser crashes with an 'Error code: Out of Memory' during firmware upgrade via image file upload.
Scope
FortiGate
Solution
Attempting to upgrade FortiGate firmware from v7.6.1 to v7.6.2 or from v7.6.2 to v7.6.3, triggers an Important warning message: 'Please refrain from refreshing the page, logging out, or doing any operations that will disconnect your connection to the FortiGate while firmware upload is in progress. Failure to do will result in operation being cancelled'.
After closing the pop-up, just before the reboot process begins, the browser window crashes with an 'Error code: Out of Memory' message.
Testing with both Google Chrome and Microsoft Edge, including in incognito mode, results in the same browser crash and out-of-memory error.
Check whether a memory leak or conserve mode is triggered during the firmware upgrade process. If memory issues or conserve mode are detected, free up system memory before proceeding with the firmware upgrade.
The issue can be resolved by upgrading the firmware using the FortiGuard server instead of manually uploading the image file.
Check also the below steps for DNS and FortiGuard reachability:
Run the commands below and check the default route information.
get router info routing-table details 0.0.0.0
get router info routing-table database
execute ping service.fortiguard.net
execute ping update.fortiguard.net
execute ping guard.fortinet.net
If the ping test is successful, proceed to update the database. Run the commands below and refresh the GUI interface:
diagnose debug reset
diagnose debug disable
diagnose debug application update -1
execute update-now
After 3 min, stop the debug using the command below:
diagnose debug disable
