У меня есть приложение Java, которое, кажется, застряло. Я попробовал kill -3, но вывод пустой (он перенаправляется в файл, но там ничего нет).
как я могу увидеть, что он делает?
ИЗМЕНИТЬ:
Я попробовал jstack, но он разбился:
Linux # /usr/pkgs/java/1.6.0.25/bin/jstack -F -l 12666
Attaching to process ID 12666, please wait...
