Top Forums Shell Programming and Scripting Kill top 5 memory uses process Post 302947786 by gandolf989 on Monday 22nd of June 2015 09:21:54 AM

If you are running a database or a web server, then either or both are likely to be in the top 5 processes for memory. You may want to look at how much memory is allocated by the applications on your server and shrink the memory pool of those applications. You would likely need to restart the applications. Hence you should probably get downtime.

If you kill the wrong process you will probably need a reboot, and if you don't change the memory allocation, you will still be short on memory after the reboot.

reboot

REBOOT(8)						    BSD System Manager's Manual 						 REBOOT(8)

NAME

     reboot, halt -- stopping and restarting the system

SYNOPSIS

     halt [-lnq]
     reboot [-lnq]

DESCRIPTION

     The halt and reboot utilities flush the file system cache to disk, send all running processes a SIGTERM (and subsequently a SIGKILL) and,
     respectively, halt or restart the system.	The action is logged, including entering a shutdown record into the wtmp(5) file.

     The options are as follows:

     -l      The halt or reboot is not logged to the system log.  This option is intended for applications such as shutdown(8), that call reboot
	     or halt and log this themselves.

     -n      The file system cache is not flushed.  This option should probably not be used.

     -q      The system is halted or restarted quickly and ungracefully, and only the flushing of the file system cache is performed (if the -n
	     option is not specified).	This option should probably not be used.

     Normally, the shutdown(8) utility is used when the system needs to be halted or restarted, giving users advance warning of their impending
     doom and cleanly terminating specific programs.

SEE ALSO

     wtmp(5), shutdown(8), sync(8)

HISTORY

     A reboot utility appeared in Version 6 AT&T UNIX.
