Помогите разобраться.
Если судить по логам, то кальмар каждую минуту выдает какую-то ошибку и перезапускается. При этом, в промежутках между перезапусками работает и даже кэширует страницы.
Почему это происходит?
Что за ошибка?
Обновил Squid до версии 2.5.STABLE12.
Не помогло!
Очистил и пересоздал кэш.
Не помогло!
Эта сволочь продолжает перезапускаться каждую минуту.
По существу, он просто падает ровно через минуту после запуска, а родительский процесс его запускает снова.
Нашел подробнейшую инструкцию по установке сквида. По ней очень тщательно установил все с нуля. Результат такой же - ровно каждую минуту сквид перезапускается.
Вот строки в логе, после которых Squid валится
