I'm not even sure this is related, but it can't hurt to try it.
 
I had something similar happening (the error was that everyone was being logged out sporadically) and no one could help me either. Then it dawned on me that pages were coming from a cache that were giving the errors.
 
I turned off cacheing and the problem went away. It may cost a bit in CPU time, but I don't have any hassles.
 
This is on a site that was upgraded from 4.7.7 directly to 5.3.

Maybe this might help or it may just be a shot in the dark!

I am using Drupal 5.3 .... and not using the Polling Module at all.

I'm gonna test on another machine a clean, clean, clean install, add
CCK, then add the link, imagefield, and date 1.6 module ... the 1.7
seems to have messed up the views.
I started getting issues when I added the date CCK field ... but that's
just speculation.

If no one from Drupal.org can tell me how to fix this ... there is NO
WAY my employer is gonna use Drupal for an enterprise-wide stable CMS ....

Thanks!
