it only work if i kill the processus but each time i use the kill -9 PID he tells that no such process is found so i research for an other PID of kibana then i rekill it the same message appear until i rerun kibana and the error dissapear.

This problem only happens if i run kibana then i let it running for a long period of time without using it, in this case when i return to the SSH sshell secure that i use i cannot exit.
