The memory usage of the ipsec process is abnormal

I find that the memory usage of ipsec processes is abnormal. A machine with 4G memory has 28 tunnels with 60% memory usage; another machine with 2G memory has 134 ipsec tunnels with 5% memory usage; even another device with 4G memory has 0 tunnels with 70% memory usage.I want to know the mechanism of memory usage of ipsec process, whether there is memory leakage, and how to reclaim the leaked memory

1.1.8 is EOL
Use LTS or 1.3 release

What does EOL mean?Upgrade to system version 1.3 can solve this problem, right?

End of the product lifecycle EOL

Ok, I see what you mean
