This could indicate that your connection table is filling up. If that
happens, hosts that have an established connection can continue to use
the net, but hosts trying to open new connections will fail. Is that
what you see?
Your best source of information is the firewall itself. Login and check
system logs, "dmesg" output, and see if anything suspicious shows up.
You can examine the connection table with
cat /proc/net/ip_conntrack
You can just get a count of how many connections there are with
cat /proc/net/ip_conntrack | wc -l
If the table is huge, you would need to examine it by hand to see what
hosts and IP's are causing all the connections.
