UpgradeWizard blank: Can't upgrade from SugarCRM 6.3.0 to 6.3.1

[javipas]

I'm trying to upgrade my SugarCRM installation but the Upgrade Wizard doesn't work at all

When I try to access the UpgradeWizard page from the admin dashboard I get the following data on the upgradewizard.log file:

Thu, 05 Jan 2012 13:49:58 +0100 [UpgradeWizard] - setting session variables...

)
Thu, 05 Jan 2012 13:50:00 +0100 [UpgradeWizard] - finish upgrading system displayed tabs and subpanels

The URL (mydomain.com/index.php?module=UpgradeWizard&action=index) gives me an HTTP500 error on Google Chrome, the rest of browsers I've tested show a blank page too.

Hopefully somebody can help. This is working with an Nginx+PHP-FPM (5.3.5)+Varnish on a Ubuntu 10.04 LTS VPS.

Try this:

Go to the folder cache/upload/upgrades/temp and delete the file upgrade_progress.php and then reload the upgrade wizard.

[javipas]

Thanks for the suggestion, but the situation hasn't changed much. I've deleted the file, and when I try to reload the Upgrade Manager, I get a 502 Bad Gateway message (I am on an nginx server, no problems with it until now).

The upgrade wizard does something, though: it creates another upgrade_process.php file, which contents the following:

 <?php
// created: 2012-01-09 13:09:11
$upgrade_config = array (
  1 => 
  array (
    'upgrade_vars' => 
    array (
    ),
  ),
  2 => 
  array (
    'start' => 'in_progress',
  ),
);
?>  

Maybe this could be useful.

Have you checked your PHP.INI to see what the memory_limit setting is at? It should be at least 128M

Checked, it was 128M, so that should wark. I've tried to find the reason for the error, and I've checked my error_log on the sugar installation. The messages shown are:

2012/01/09 20:20:35 [error] 25466#0: *572 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 95.18.99.137, server: sugar2.mydomain.com, request: "GET /index.php?module=UpgradeWizard&action=index HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm-mydomain.sock:", host: "sugar2.mydomain.com", referrer: "http://sugar2.mydomain.com/index.php?module=Administration&action=index"

The favicon error isn't important, but the first 104 error is the one that makes me think what's happening. It's strange, because the rest of the sugar installation works fine.

BTW, thanks for your quick answers. Hopefully this way I can find the answer...
