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 >

Hi, I''ve setup a gateway using multiple default gateways and netfilter MASQUERADE to load balance traffic between two DSL interfaces and one dedicated link, and when I try to download something big, or when I''m using MSN (both in clients under this gateway), sometimes, or most times, after a while the connection timeouts. The connection doesn''t seem to change its

Hey guys, I have several Linux routers in place at high-usage locations (student apartment complexes). I''m having trouble with some of the routers which use 6Mbit DSL lines as their Internet feed. The routers use PPPoE and perform NAT. During peak usage periods, the routers are dropping alot of packets. I''m lead to believe this is because there are too many active

Hi, all When use Centos 6.5,kernel version 2.6.431, I have continuous messages of "Neighbour table overflow" in messages. I have modified the gc_thresh1(512) , gc_thresh2 (2048) gc_thresh3 (4096) in /proc/sys/net.. path, But the messages occurs occasionally. some forum saied: They are probably realted to a kernel bug where the thresholds are in fact only half of the value that is set.

I''ve got a linux router pushing 600-1000 pppoe connections through it. I''m getting a screen error "Neighbor Table Overflow" after this box has been up for between 1 week and 1 month. When this is happening, routing slows to a crawl if at all. Then dies. I''ve added: # Added to stop "neighbor table overflow" messages in the kernel

Hi, I have a P4 @ 3Ghz router running Debian. It shapes traffic ( about 500-600 classes ), about 1000 iptables rules, and it does BGP too, so i get about 1300+ routes in the routing table. The problem is the load is too high on this system. I found a solution to my problem, turning off the route cache, but i dont know how to implement it, I was wondering if anyone found a way to disable the

Hi, I regularly have errors (kernel: dst cache overflow) and crash of a firewall under Linux 2.6.17 and the route patch from Julian Anastasov. With rtstat I see that the route cache size increases regularly without never decreasing.

OK please try the following patch [PATCH] neighbour: fix a race in neigh_destroy() There is a race in neighbour code, because neigh_destroy() uses skb_queue_purge(&neigh->arp_queue) without holding neighbour lock, while other parts of the code assume neighbour rwlock is what protects arp_queue Convert all skb_queue_purge() calls to the __skb_queue_purge() variant Use

Dear Dr. Bivand and R-users, I have a 5 by 5 grid, say, location[1:5,1:5], and I want to know the indices of 8 neighbours of each cell. For example, for location[2,2], its neighbour coordinates are [1,1:3], [2,1], [2,3] and [3,1:3]. Sometimes I also need to remove edge effects (torus = TRUE). I have tried "cell2nb" function in your spdep package. Here's my example: > neigh
