WordPress database error “Query was empty”

WordPress database error Query was empty for query made by do_action_ref_array, call_user_func_array, do_all_pings, do_trackbacks, trackback

I am getting the above error quite frequently, almost every minute. The has seem to slow down quite a bit since receiving this error. I couldn’t find anything through google or the forums.

I’ve disabled my plugins, checked my php for bad code, and spoke with my host. I can’t seem to resolve this issue.

Thank you
