Ouch! This looks like an awful AB/BA deadlock. Indeed, fwrr_get_server_from_group() wants the lbprm lock and will grab the server's lock while fwrr_update_server_weight() wants the server's lock to be held and will use the lbprm lock :-( I need to revisit all this then :-( Thanks for the report, it's extremely useful!
