Здравствуйте.
Периодически (каждые несколько минут) сыпятся в лог ошибки:

Причем:
- 21 устройство подключено непосредственно к /dev/ttyRS485-1 самого контроллера, других устройств там нет, длина провода 30см
- 23 устройство подключено к WB-MGE v.1, других устройств там нет, длина провода 15см
- 24 и 66 устройство подключено к другому WB-MGE v.1, других устройств там нет, общая длина шины 30см
- 33 устройство подключено к WB-MGE v.2, других устройств там нет, длина провода 15см
Таймаут ответа на всех портах 800мс.
Но при этом в целом устройства работают нормально, скорость реакции в данном случае не критична. Т.о. беспокоит просто простыня однотипных ошибок. Подскажите куда копать?
