Answer Posted / sushil
if all the commands are hanging then there is no point
running any command.
In this case system can be considred as it's hung. and hence
u might want to
collect some useful information to perform root cause
ananlysis before rebooting the
system.
Here we can apply magic keys and ask OS to dump memory/
registers and we can even
instruct it to terminat/kill all but init process ,
sometimes we can send
kill signal to all proccess including init.
Alt+SysRQ+m prints memory information to the console.
Alt+SysRQ+e sends SIGTERM to all processes except init.
Alt+SysRQ+i sends SIGKILL to all processes except init.
Alt+SysRQ+l sends SIGKILL to all processes, inclusive init.
Alt+SysRQ+s writes all data from the disc cache to the
harddiscs, its a sync
Alt+SysRQ+i (for the processes that didn't listen for the
TERM signal, this is a kill -9 process)
Alt+SysRQ+b (reboot).
