I have a fairly complex issue.

We have Drupal 6.x running on 3 web nodes, with varnish on each, and a database server that also is running one instance of memcache.
In one memcache bin we have cache and in another we have cache_views.

Randomly, the views for our cck content_type_* (all cck related tables) items just stop querying the table with the cck data in it.
This failure affects almost every aspect of our website and is almost impossible to trace.

What we know:

1. The query never pulls back data from the content_type_* table.
2. Dumping memcache bins fixes the issue
3. Flushing all caches fixes the issue.

We currently think it has something to do with the modules weights - the order in which they are firing. Has anyone ever run into this kind
of issue? If so can you please explain what you did to resolve the issue?

Please respond for any more information if it helps.

Hey,

I think we might have a similar problem here. Sometimes our Views pages will show up without the CCK content being displayed. We also use memcache and dumped the content_type_info:en and views_data:en fields in memcached when the problem occurred. We are finding that views_data is missing the CCK fields when it caches what CCK fields are available. This problem happens very rarely for us, so we're assuming that a specific event triggers it.

Let me know if you figure it out or able to resolve it. I'll keep you posted if I find anything, also.

Munskey, do you see your missing cck data tie to load at all? memcache reads/writes ?
