It seems there is an unsafe access to the scoreboard procs in fpm_status_handle_request. The scoreboard is copied under a lock, but later scoreboard procs are copied from scoreboard_p without locking. 
This was pointed out to me by bukka in .
The risk of this is pretty low. The only impact in can imagine being inconsistent readings on the status page.
