Добрый день коллеги. Имеется 2611 + VWIC 2MFT-E1-DI. В карту проключен поток с мультиплексора ЦРРЛС. Пока поток не пользовали проблему не замечали. Но вот с приходом активного трафика начались проблемы. Время от времени в логи валится следующее:

Зависимости падений обнаружено не было. На этой же ЦРРЛС работает куча другого оборудование, включая циски. Но правда работают на конвертерах V.35<->G.703. Каналы с конвертерами работают годами. В чем может быть проблема??
