Good afternnon:

Thank you very much all of you for your help

This is 1 of 4th web application node using apache as a webserver, and as a Production env it receives all the htpp traffic from internet throuh a load balancer called (F5 -A10) and by a java process called germ.jar open sockets to port 89xx (load balancer), so below is the information:

Code:
$ /bin/bash --version
GNU bash, version 4.2.46(2)-release (x86_64-redhat-linux-gnu)

Code:
$ uname -a
Linux serverbam04.nh 4.1.12-124.15.2.el7uek.x86_64 #2 SMP Tue May 22 11:52:31 PDT 2018 x86_64 x86_64 x86_64 GNU/Linux

Code:
openjdk version "1.8.0_171"
OpenJDK Runtime Environment (build 1.8.0_171-b10)
OpenJDK 64-Bit Server VM (build 25.171-b10, mixed mode)

webserver apache

Code:
EE-plus-7.0.2/lib/openejb-javaagent.jar -Djdk.tls.ephemeralDHKeySize=2048 -Djava.protocol.handler.pkgs=org.apache.catalina.webresources -classpath /usr/share/tomEE-plus-7.0.2/bin/bootstrap.jar:/usr/share/tomEE-plus-7.0.2/bin/tomcat-juli.jar -Dcatalina.base=/usr/share/tomEE-plus-7.0.2 -Dcatalina.home=/usr/share/tomEE-plus-7.0.2 -Djava.io.tmpdir=/usr/share/tomEE-plus-7.0.2/temp org.apache.catalina.startup.Bootstrap start

The reason why i asked whad does kill -9 -1 does is because our web application provider suggested every time we shut down the app, i will have to run this command to make sure all session are cleaned, but i didnt know how powerful or dangerous this command will be

some time ago the user med has 1615 processes because a shell that runs every 5 minutes got stuck and blocked the node, and we contact aour System Administrator but these processes could never get killed and this node had to be started

Code:
med+ 32737     1  0 14:49 ?        00:00:00 /bin/bash /app/perm/backend/check_port_process/CHECK_PORT_PROCESS_MAIN.sh
 32742     1  0 13:15 ?        00:00:00 /bin/bash /app/perm/backend/check_port_process/CHECK_PORT_PROCESS_MAIN.sh
$ ps -fu med|wc -l
1615

kill command
Code:
ps -fu med | grep -v grep | awk '{print $2}' | xargs kill -9

Thanks again for your help

KILL(1) 						      General Commands Manual							   KILL(1)

NAME
kill - terminate a process with extreme prejudice SYNOPSIS
kill [ -sig ] processid ... kill -l DESCRIPTION
Kill sends the TERM (terminate, 15) signal to the specified processes. If a signal name or number preceded by `-' is given as first argu- ment, that signal is sent instead of terminate (see sigvec(2)). The signal names are listed by `kill -l', and are as given in /usr/include/signal.h, stripped of the common SIG prefix. The terminate signal will kill processes that do not catch the signal; `kill -9 ...' is a sure kill, as the KILL (9) signal cannot be caught. By convention, if process number 0 is specified, all members in the process group (i.e. processes resulting from the current login) are signaled (but beware: this works only if you use sh(1); not if you use csh(1).) Negative process numbers also have special meanings; see kill(2) for details. The killed processes must belong to the current user unless he is the super-user. The process number of an asynchronous process started with `&' is reported by the shell. Process numbers can also be found by using ps(1). Kill is a built-in to csh(1); it allows job specifiers of the form ``%...'' as arguments so process id's are not as often used as kill arguments. See csh(1) for details. SEE ALSO
csh(1), ps(1), kill(2), sigvec(2) BUGS
A replacement for ``kill 0'' for csh(1) users should be provided. 4th Berkeley Distribution April 20, 1986 KILL(1)
