Всем привет. Словил очень странную проблему и в первый раз.

На сервере постоянно происходит рассинхронизация системного времени. На ночь, выключил астериск и на утро заметил, что со временем все хорошо. Включил астериск и в течении часа, время рассинхронезировалось. При рестарте chronyd, время синхронизируется сразу. Потом в течении 1-2ч снова время кривое.

В наличии:

Centos7, asterisk 16, apache, iptables, chronyd default config.

Астериск поставил наднях. Ради него весь этот сервер поднял (новый). Аналогичный сервер поднимал год назад, там все работает до сих пор хорошо. Инструкцию по настройке систем использовал этого сайта.

Chronyd теряет источник, как я понял. NTP server ставил и дефольный и локальный. Результат одинаковый.
