Upgrade to 4.0.10. 408 Request Time-out. 503 Service Unavailable
I tried to auto-upgrade 4.0.9 to 4.0.10 4.0.10.
But I get errors. It is 408 Request Time-out or 503 Service Unavailable.
I go to admin console and click "Upgrade" link. Than I wait for long time 5min or more and get one of these errors.
I have ran that update script for many times before (for many previous versions) it work quick and cause no problem.
And I never got 503 error for other scripts
