This issue occurs:
The default value held by this entry varies heavily depending on how much memory you have. On 128 MB of RAM you will get 8192 possible entries, and at 256 MB of RAM, you will get 16376 entries. You can read and set your settings through The / proc / sys / net / ipv4 / ip_conntrack_max setting.
Chinese:
Connection tracking table energy accommodation is controlled by a variable, which can be set by IP-Sysctl function in the kernel. The default value depends on your memory size, 128MB can contain 8192 catalogs, 256MB is 16376. You can also view, setup in / proc / sys / net / ipv4 / ip_conntrack_max.
Solution:
1. Write in the boot from the startup file:
Echo $ Number> / Proc / Sys / NET / IPv4 / ip_conntrack_max // $ number = 16376 * times (memory is a multiple of 256M)
2, in /etc/sysctl.conf plus:
Net.IPv4.ip_conntract_max = $ number
