Description Jay Shaughnessy 2010-06-14 19:38:21 UTC
I think this may happen when a new version of a plugin is being registered. It may not actually have to be different from the db version of the plugin. I'm not sure.

Anyway, during plugin registration you get a failure (full trace attached) with a root cause like the following:

I don't currently have any reproduction steps, but I've seen this more than once.  The server startup continues but is most likely invalid from that point on.  A subsequent restart may normalize the situation but I'm not sure.

Dropping priority until able to reproduce

Comment 3 Jay Shaughnessy 2010-07-20 20:59:47 UTC
I believe the root cause for this is the same as 616395. Closing as duplicate.
