[strongSwan] "signal of type SIGINT received. Shutting down" ?

[Anvar Kuchkartaev]

I had similar type of error and it was kernel-libipsec plugin was conflicting with selinux. I disabled the kernel-libipsec and issue has been resolved.

Hello list,

I don't understand why one of my StrongSwan clients disconnects from its
server.
When it happens, it begins with this entry in the logs :

Jan 17 21:12:59 yomama charon: 00[DMN] signal of type SIGINT
received. Shutting down


Then :

So basically StrongSwan restarts, I can't figure out why, and I lose
packets.

Where should I look ?

Thanks !
