The only time I saw my conntrack table getting full was when there was a computer running another OS with some backdoor or virus on it that was sending a lot of packets, the Linux box couldn't handle all those packets and became so slow I couldn't even log in. Took me a while to figure out that one. Check in your /proc/net/ip_conntrack to see why your table is full. -- Jean-Rene Cormier <jean-rene.cormier@xxxxxxxxx>
