I have made no changes to these in about 4 years. Thanks Thomas Dukes <tdukes at sc.rr.com> wrote: 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?
