ip_conntrack table filling up, dropping packets
...f "ESTABLISHED" tcp connections from my webserver (the src is my
webserver ip), and some other random connections to my webserver, and
many "ASSURED" connections. So why is it filling up? I changed the
default timeout value like so:
echo 36000 > /proc/sys/net/ipv4/netfilter/ip_conntrack_tcp_timeout_established
but I don't think that's had any effect. any thoughts? what additional
info can I provide that would be helpful? I did find a script that

Conntrack table full and Heavy p2p loaded traffic manager ...
...:26:19 gestor1 kernel: printk: 38 messages suppressed.
Feb 23 14:26:19 gestor1 kernel: ip_conntrack: table full, dropping packet.
The server is celeron pentium 4 based 3Ghz + 512Mb ram
Does anyone could suggest me what are the best value for
net.ipv4.netfilter.ip_conntrack_max
net.ipv4.netfilter.ip_conntrack_tcp_timeout_established
Might be I can tune other kernel value ?
Thanks for your help

ip_conntrack: falling back to vmalloc.
...39;ve use this "math" to calculate it :
(3072 - 256) x 1024^2 - 236 = 12511822,1027
The near "power of 2" seems to be 2^23 = 8388608
With this result I''ve change my "sysctl.conf" file
net.ipv4.netfilter.ip_conntrack_max = 8388608
net.ipv4.netfilter.ip_conntrack_tcp_timeout_established= 28800
and I''ve to change the HASHSIZE to ip_conntrack_max / 4 ...
What is wrong ! How can I solve the problem ...
I''m waiting for a server with 8Gb (8192) of ram most of available to
use with conntrack !
