У меня есть приложение JVM, которое случайно падает, и ни один из разработчиков не настолько хорош в анализе приложений Java (ирония судьбы). При заливке через выход я вижу тонны ниток с состоянием _thread_blocked. Это нормально?
Поведение, которое мы наблюдаем, это то, что приложение будет работать и оставаться в течение неопределенного времени - от 10 минут до 6 часов - затем оно неожиданно завершит работу (обычно через SIGSEV), однако ничего нет в журналах приложений, системных журналах, dmesg, mail или любых других закоулках, которые linux любит помещать сообщения. Нет ничего, кроме дампа ядра.
Я разместил часть дампа основной памяти ниже (все это слишком велико для SO) и ссылку на полную версию дампа. Если у кого-то есть идеи, я открыт для них.
