Я пытаюсь определить причину сбоя сервера Android ADB и выводит список segfault, который приводит к тому, что при перезапуске ADB несколько устройств отображаются в списке как offline.Мы проводим различные Appium тесты на множестве Android телефонов.Эта проблема возникла недавно, когда серверный процесс Android ADB будет завершен с SIGSEGV, а затем мы должны перезапустить сервер Android ADB.
Когда возникает проблема со сбоем сервера adb, мы видим, что он вызываетUSB отключения в журналах dmesg.После перезапуска adb эти устройства отображаются как «отключенные», и они никогда не возвращаются к available.Я полагаю, что offline вызывает появление отключений dmesg.
Вопрос
- Как мы определяем, почему происходит этот segfault и что устройствабыть переведен в режим
offline? - Есть ли способ вывести эти устройства из
offline через командную строку (возможно, через ОС или подсистему USB?
Спасибоyou
