Imap ошибка протокола tls неверная запись mac decryptmissingdatabytes

Здравствуйте, такая проблема случилась пару дней назад, не работает полностью mail, нельзя ин отправлять ни принимать почту.
Также в это же время закончилась лицензия на Касперского, возможно как то с этим связано, но не хочется в это верить. Есть ли решение, чтобы The bat работал без Касперского?????

Ошибка:
     IMAP  — Ошибка протокола TLS: Неверная запись MAC DecryptAEAD.
     IMAP  — Соединение с IMAP-сервером imap.mail.ru, порт 993
     IMAP  — Начинаю приветствие TLS

Здравствуйте. 
Ежедневная проблема с Kaspersky Security Center установленным на Windows Server 2012r2.

 
Каждое утро заходя на сервер вижу сообщение:
«Не удалось подключиться к Серверу администрирования «localhost». Укажите другой адрес или попытайтесь подключиться еще раз.»

 
При этом в отчете «События аудита» появляется сообщение:

 
Имя события Сервер остановлен
Важность: Информационное сообщение
Программа: Сервер администрирования Kaspersky Security Center
Номер версии: 10.1.249
Название задачи:
Компьютер: Сервер администрирования <имя>
Группа: <имя>
Время: 26 декабря 2014 г. 2:00:02
Имя виртуального Cервера:
Описание: Остановлена служба Сервера администрирования

 
При перезапуске приложения вручную все работает нормально до следующего утра. Подскажите, что делать?

Я использую клиент Apache CXF, работающий в виртуальной машине Windows Java 1.6.0_29-b11 для подключения к мэйнфрейму IBM (я полагаю, это zSeries) и вызывается работающая там веб-служба SOAP. Соединение выполняется через SSL/TLS, и большую часть времени работает нормально.

Однако время от времени у меня есть SSL-исключения с сообщением bad record MAC. Вот результат работы программы с использованием свойства javax.net.debug.

К сожалению, у меня нет возможности изменять или отлаживать конечную точку на сервере.

Что может быть причиной этого?

Как я могу выделить и исправить это поведение?
