what is your netmask?
eth0 = 255.255.240.0
That is 4096 addresses (256*16).
eth1 = 255.255.255.0 lo = 255.0.0.0
lo is correct. The 'whole' net127. Of which 4 addresses have ever been used (that I have encountered)....
These don't look right except for eth1. I have made no changes to these in about 4 years.
Thanks

Just started getting this. I tried the following by adding it to my etc/sysctl.conf: net.ipv4.neigh.default.gc_thresh1 = 4096 net.ipv4.neigh.default.gc_thresh2 = 8192 net.ipv4.neigh.default.gc_thresh3 = 8192 net.ipv4.neigh.default.base_reachable_time = 86400 net.ipv4.neigh.default.gc_stale_time = 86400 That pretty much locked things up. Then I tried another googled solution: echo 256 > /proc/sys/net/ipv4/neigh/default/gc_thresh1 echo 512 > /proc/sys/net/ipv4/neigh/default/gc_thresh2 echo 1024 > /proc/sys/net/ipv4/neigh/default/gc_thresh3 And adding it also to etc/sysctl.conf: net.ipv4.neigh.default.gc_thresh1 = 256 net.ipv4.neigh.default.gc_thresh2 = 512 net.ipv4.neigh.default.gc_thresh3 = 1024 Still not working. Any ideas? TIA _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos*Yahoo!
