Maybe the problem is the number of clients doesn't decrease when a client disconnects? It's possible to send a "goodbye" message to the server, but sometimes the connection gets lost without a chance to say anything, in which case a timeout (and maybe a keep-alive message) might help. Also, why is the initial number of clients set to -1?

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
