Excessive page loading in Confluence post-migration of server

[Michael Johnson]

Hi All,

I recently migrated our Confluence TEST instance from the old MS Server '12 VM to a new '16 VM, just the application not the DB.

The instance is up and all functionality appears normal however in FF and Chrome, the page continues loading for up to a minute or more after all the content is loaded. Oddly, IE and Edge are not displaying the same behavior. It doesn't seem to matter what content is on the page as we see the excessive loading times even on a blank page, and it's pretty much consistent across the whole instance meaning all spaces/pages.

Some already tried solutions are deleted plugin cache, rebuilt index from scratch, ran in safe mode, and prob a few others. I'm seeing a lot of errors in the logs that point to the issue described in the link below however even with Team Calendars(and all plugins at one point) disabled, the issue persisted.

Any new ideas would be appreciated.

Best, Michael J

Atlassian support pointed me in the right direction shortly after I posted this. Was traced to our custom site icons, reset to default and the problem ceased. Re-applied the custom ones and the issue did not return. Just in case anyone else sees this issue.
