Dashboard showing up blank after a period of time

Hi guys,

I’m tracking traffic of approximately 3 million page-views/week. Archiving and deletion of older entries have been enabled, but even so, the piwik dashboard tends to become inaccessible(blank) over a period of time, forcing me to do manual purges to make it work again.
Archive.php is running every hour till completion.
I’ve used the CustomVariables plugin to capture user navigation data in the application, could this be contributing to the problem?

Any help would be greatly appreciated!

Have you disabled “Browser trigger archiving” as per instructions in: http://piwik.org/docs/setup-auto-archiving/

If this is disabled the dashboard should load fast at all times. Hope it will work for you!
