kill -9 actually closes the process no matter what. So it seems like your process is getting stuck and needs to be killed with -9 rather than -15. Regards, KDSys.

Kill signal : SIGTERM: 15: Termination signal - allow an orderly shutdown: SIGSTOP: 17,19,23: Stop the process: This is a BASH shell builtin, to display your local 7. kill (Terminate) You can send signals that terminate processes, such a command is aptly named the kill command. $ kill 12445.

The SIGTERM signal is sent to a process to request its termination by allowing it to cleanly release its resources and saving Mar 08, 2007 · Great, I'll just give it the application log path and it will kill the process if I supply the -k option. Unfortunately, this send a SIGKILL to the process. The java process is written to catch a kill signal (SIGTERM) so that it may shutdown gracefully. Is there a way to make fuser send a SIGTERM instead of SIGKILL?
Most system administrators will usually resort to the more abrupt signal when an application doesn’t respond to a SIGTERM: The -9 tells the kill command that you want to send signal #9, which is called SIGKILL. With a name like that, it’s obvious that this signal carries a little more weight.
When we issue kill -15 which in Linux is called SIGTERM. A SIGTERM means termination signal. It is an OS-level system call which commands process stop. When we issue SIGTERM, the parent process again signals to its child process to stop them which were forked from the parent process. kill -TERM 907 2331 19052 kill -SIGTERM 907 2331 19052 kill -n 15 907 2331 19052 kill -s 15 907 2331 19052 kill -s TERM 907 2331 19052 kill -s SIGTERM 907 2331 19052.

Ahh! I think SIGKILL/9 - the premeditated savage murder of a process - is my personal favorite so much more satisfying than SIGTERM/15 - to just telling the process to "shut-up and die!" (but clean up after yourself first). kill -9 xyz to kill a process that is so stubborn that a simple kill is not powerful enough to kill. So, what does -9 mean?
