本文介绍如何通过调整系统参数来解决因并发连接数过多导致的Conntrack资源限制问题。文中详细解释了如何查看当前开放会话数量及最大限制，并提供了增加最大并发连接数的方法。

This is telling me that you are trying to send out requests for more
servers than you have available conntrack entries.

# This tell you how many sessions arte open right now.
cat /proc/net/ip_conntrack | wc -l
# This tells you the maximum number of conntrack entries you can have in
total
cat /proc/sys/net/ipv4/ip_conntrack_max

Once the previous number hits beyond the latter, you should start seeing
these messages. I would increase the latter number by calling:

echo "<some_bigger_number>" > /proc/sys/net/ipv4/ip_conntrack_max

or if you want it to span reboots, you can place the following in
/etc/sysctl.conf

sys.net.ipv4.ip_conntrack_max =3D <some_big_number>
or:

sysctl -w net.ipv4.ip_conntrack_max="32768"
