Answer 1

benim anladığım kadarıyla shutdown ederken, session kill edilemediğinde biz shutdown desek bile aynı port üzerinde açık session kalmaya devam edilebiliyor. Veya ayakta olan bir uygulama ise zaten kullanıldığına dair böyle bir uyarı mesajı verebiliyor.  Benim çözümüm ls -i komutuyla ilgili çalışan session ı bulup "kill -9 PID" ile kill etmek yani session'ı manuel durdurmak gerekir. PID çalışan session 'ın IDsi oluyor , process ID.
