sitecore, error updating index - LockRecursionException

Question

I'm getting the following error when updating the index for a single item. I don't have a clue where to start. My instinct is the fully rebuild the index, but this likely would generate the same error again?

anagedPoolThread #79 15:22:51 INFO  Starting update of index for the database 'master' (3 pending).
ManagedPoolThread #60 15:22:51 INFO  Starting update of index for the database 'web' (3 pending).
ManagedPoolThread #60 15:22:51 ERROR Could not update index entry. Action: 'Saved', Item: '{2845828F-1CBC-4F6B-AFC5-8558E8C472A0}'
