[AusNOG] Cisco LNS - dataplane errors

[Joseph Goldman]

Hi John,

  It was initially set much higher than the subscriber count, we also 
removed it completely and to no help - we have since rebooted the router 
which seems to have fixed it but it has now stalled twice since that 
reboot so thinking quite likely faulty hardware, we are in the process 
of cutting over to backup hardware now *sigh* thanks for the look-in though.

Thanks,

Joe
