tcp_ack+633 reoccuring error

ReadyNAS 314 system

ReadyNAS 626 on the same network and has had no errors

The 314 has had three of these errors in past 6 months. 

 

Had to hard reset with removal of power -- device did respond to RAIDar or to front panel. 

Currently rebuilding.

 

Posts to the forum seem inclusive regarding this specific error.

The 314 NAS has about 80% of disk space available on both mounted volumes.

 

Is there any data regarding whether this is a real hardware error or a software issue that occurs in a 'race' condition or a random act of the Computer Gods? 

It seems unusual that it would only occur on this particular system and not its adjacent system.

    Does the RN314 use link aggregation/bonding?

      No.

       

      Topology is simple one dimensional LAN with clients, router (DHCP server duties) and AP devices, and about 10 fixed IP devices (ReadyNAS units, cameras, etc.)

        The tcp_ack+633 is a crash in the NAS software.  One possible cause is a failing NIC in the NAS (unfortunately not repairable if that is the case).

         

        I suggest swapping cables with the RN626 just to rule that out (though a failed cable is unlikely).  Another thing you can try is switching to the other NIC.
