FSV318N connection drop and kernel emergencies and errors in log

Here are some of the messages that appear on my syslog server:

[Kernel] Should overwrite TID here for NULL data

[Kernel] xt_TCPMSS: bad length (589 bytes)

[Kernel] <sppe_cmd_arp> Fail to delete IPv4 ARP entry

 

according to my isp, the line is stable. according to my previous isp (yes I have changed isp's to check if it was their fault)

it was ARP table related.

The connection gets back online in about a minute or so.

I have the latest firmware :

Firmware Version:4.3.5-3

 

These connection drops make me trust netgears stability less every day.

 We have a win2012r2 webserver behind it (opening port 80 and the port for ssl and ftp) which should be up and running 24/7

    Hi simstars,

     

    Welcome to our community!

     

    It seems that you were having issues with arp table. Have you tried to enable/disable the arp broadcast? Go to Network Configuration > LAN Setup - Advanced(Upper right corner) - Enable ARP Broadcast then hit Apply.

      it's on by default. Disabling it seems not like a solution to me. Seems like a workaround.

      and what about the other two messages:

      [Kernel] Should overwrite TID here for NULL data

      [Kernel] xt_TCPMSS: bad length (589 bytes)

       

      especially the first one does appear a lot in the log.

        simstars,

         

        Yes, you are correct. That is just part of our workaround to see if that would work. You may also try to flash the firmware.
