This is the only similar error report I can find… here was a potentially helpful reply:

Last time that happened to me, it was “plugins go wild” and there were ridiculous amounts of extra entries in my meta tables in the DB. I have also seen this with bad plugins in general for whatever reason. It could also come from a bad plugin on the WP side of things if you have integration. First place I would check would be the user and site meta tables for both bbPress and WP.

Curious how your meta tables look… and if they have extra entries, which plugin is being “bad”!
