Intermittent 500 Errors Instead Of Ad Creative

[billcravens]

Hi everyone. I'm new to the Revive community, having just migrated from DFP. We've noticed that, in the days since the migration, our total ad impressions are lower than we expect them to be -- and than what our Google Analytics data suggests they should be, all things equal.

 

In troubleshooting, I noticed that occasionally, the JavaScript console returns a message indicating that instead of ad creative, a 500 error is being returned:

 

Failed to load resource: the server responded with a status of 500 (Internal Server Error)

http://ads.301digitalmedia.com/www/delivery/ajs.php?zoneid=5&cb=74309747060&charset=UTF-8&loc=http%3A//www.wably.com/

 

When navigating directly to the ad URL, we don't usually see issues, except every so often, a blank page is returned, which correlates with the following errors in the Apache error log:

Because it doesn't happen too consistently, I'm not sure exactly why it's happening.

 

The Revive instance was just installed a few days ago, with the following specs: 

Revive Adserver v3.0.5 running on Apache 2.4.7, PHP 5.5.9-1ubuntu4.2 and MySQL 5.5.35-1ubuntu1

 

Any help in pinpointing/resolving the root cause would be greatly appreciated.

Hi,

 

Check to the mysql.php file in the following path,

 

lib/OA/Dal/delivery/mysql.php

First thing I would recommend would be to run Revive on a Linux OS (CentOS 6) for maximum performance.

Check www.revive-adserver.com/support/requirements to make sure you have all modules loaded on your server.

Also check your user and group permissions to make sure they are set correctly.
