Watchdog stuck ip

After recover binary backup on identical hardware (CCR1072, v6.49.6), became problem with stuck ip address in watchdog. Even if i change ip (winbox or telnet), in suppout file i see the first one ip address after recovering. And my router reboot with watchdog because cant ping this ip address. I disable watchdog, but its not a solving of this situation, i need him.

Previous CCR1072 with same software version has problem with periodicaly reboot because watchdog did that, but not through of ping ip address, just like that…
