Thank you.
This would imply that the /etc/sysctl.conf is already filled with the right values. We have far more than 1024 nodes in the network. The filling can be done by a proper make-fai-nfsroot hook. BTW, I did not find much documentation about this which might be my fault. Does it work as the usual FAI hooks? I got this warning message already in the live initrd. It might help to write a script for the initrd which echos a reasonable cache sizes values into /proc/sys/net/ipv4/neigh/default/gc_thresh1-3 Cheers, Henning
