Killing stuck process

Arista:
# bash
$ ps –ef | grep -i Stp
$ sudo kill PID

CheckPoint:
ps -auxww  Report all active processes in the kernel we can see zombi process with this command  (z)
You must first identify the parent process of these zombies;
ps -l -p <pid of zombie>
pidof fwd (splat)
pgrep -l sshd   Find the PIDs of processes by (part of) name
ps axjf              See in tree format also i can see parent pid )
pmap PID       Memory map of process (good for hunting memory leaks)

Displaying the top 10 CPU-consuming processes (% of total usage)
ps aux | head -1; ps aux | sort -rn +2 | head -10
Displaying the processes in order of real memory use
ps vx | head -1 ; ps vx | grep -v PID | sort -rn +6 | head -10

Displaying the processes using whatchdog (CPWD) for  (CDP,FWM,FWD)

******************************************************
Kill a Firewall process
kill -9 (pid of process)
fw kill [-t sig] proc_name
Example:
fw kill -t 9 fwm
Also process can be kill with top command and just press -k follow by process PID

Cisco:
# show processes cpu sorted
# clear sockets PID

F5
# ps ax | grep -i sshd
# kill -9 PID

-for example we want to check dhcp PID
# fnsysctl more /var/run/dhcpd.pid
71
-to kill dhcpd
# diag sys kill 9 71
or
# fnsysctl kill -9 71
-to disable dhcpd service
# config sys dhcp server
# edit 1
# set status dis
-to enable back
# set status ena
