I have my RedHat Linux 9 with the above message pop-up several times. What is the meaning of that, and the way to stop this from coming out.

check files
/proc/sys/net/ipv4/ip_conntrack_max
/proc/sys/net/ipv4/netfilter/ip_conntrack_max

double (or whatever those entries), eg if it shows 4096
echo 8192 > /proc/sys/net/ipv4/ip_conntrack_max

also, You can make it permanent in /etc/sysctl.conf by adding line
net.ipv4.ip_conntrack_max = 8192

I looked at /proc/sys/net/ipv4/ip_conntrack_max, it read 16376.  Do I need to double it ?

I do not find any /proc/sys/net/ipv4/netfilter folder.

Just what is it suppose to mean ?

Yes double it(or grow). Then Your box would be able to handle more concurrent connections.
/proc/sys/net/ipv4/netfilter appeard in newer kernels...

Another Q is why Your box have so much connections in its conntrack...

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

ravenpl,

rather than to allow more concurrent connections, can I have other solution, I am afraid more concurrent connections will lead to more slow traffic, which will affect the whole network.

My site is to provide news channels for pda use. (whole process involve several php coding to get contents from other sites and convert them to codes suitable for use by PDA, something like a provider for Avantgo.
