+unix.handle_sigtstp                    | Handle SIGTSTP and SIGCONT signals. Disabled by default
+
+`handle_sigtstp` enables handling of SIGTSTP and SIGCONT signals. (~will be added in 2.43.0~)
+
+SIGTSTP can be called using Ctrl+Z in terminal with running i2pd in it or by `kill` command. When signal recveived, i2pd will switch to offline mode and stop sending traffic and cleaning of netDb. All active tunnels will be frozen.
+
+To restore network connectivity you need to send SIGCONT signal to proccess. Tunnels will be cleared if they should expire during the frozen state time and new ones will be built.
