Hello, I am doing some investigation regarding an error I am experiencing using my linux embedded device as router in my home network.
If I try to push the number the connections to around 20K I will se a lot of messages from the kernel saying : nf_conntrack: table full, dropping packet. nf_conntrack: table full, dropping packet. nf_conntrack: table full, dropping packet. nf_conntrack: table full, dropping packet. nf_conntrack: table full, dropping packet. nf_conntrack: table full, dropping packet. nf_conntrack: table full, dropping packet. Actually this is fine for me since the number of allowed conntrack is /proc/sys/net/netfilter/nf_conntrack_max is around 7844, the strange thing is that the device will reboot after a while - actually my watchdog reboots the device since is not able to allocate memory - I have a try with slabtop running and I have seen that but monitoring the /proc/slabinfo: 3968 nf_conntrack_c0d4eacc 4392 size-8192 6360 skbuff_head_cache 15356 size-4096 31808 size-1024 Well size-1024 is quite high, do you know where is that from and how is that related to the packets coming in ? Even point me at the right folder in the source code could be great since I am really lost here. Thanks in advance, Pietro. _______________________________________________ Kernelnewbies mailing list [email protected] http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
