Working on tracing an issue where a "clear all caches" causes all panels to go blank. Culprit appears to be that the Ctools Object Cache table is being insufficiently or incompletely rebuilt.

I have seen this happen once or twice updating between versions, but it wasn't persistent. Now it's persisting. May be a bad custom plugin, but there are no warnings or errors that I can detect.

Will post more info as I'm able.

the ctools_object_cache table is non-volatile storage for temporary data and cannot be rebuilt. It should never be cleared except for the cron job which clears stale objects.

The clear all caches button does not clear this table.

Additionally, the object cache should not be used for rendering panels at all. It is only used to store user input during the editing process.

Maybe I'm on the wrong path then.

What I'm seeing is that no panes render after cache clear from the admin_menu module. Going via admin/settings/performance does not have this problem.

Joshk, when you refresh the page, do the panes render as expected?
