виснет pppd-2.4.3

[digitalm]

Иногда подвисает pppd на сервере dial-up. Звонки принимает mgetty. Модемы сидят на 8-портовой Cyclades.

Периодически возникает ситуация, когда pppd пишет в лог Connection terminated, а сделать exit при этом почему-то забывает.

Может в опциях что-то не так?

Откатился на ppp-2.4.1 пока полет нормальный.
