I updated my kernel rpm from kernel version kernel-3.10.0-693.el7.x86_64 to kernel version kernel-3.10.0-957.1.3.el7.x86_64.After update, a process named watchdogd with pid 49 is continuously running at the background.

I think this process is kernel invoked.

Is there any way to rename kernel processes or is there any way we can manage the startup processes in RHEL 7.4 ? I am unable to find any watchdogd.conf file or any watchdogd.service on my system.

Which script is responsible for startup of these processes and is there any way to change that script or change the startup process name?

Command Used:

ps -ef | grep -i watchdogd

Output:

root 49 2 0 04:03 ? 00:00:00 [watchdogd]

root 1592 1563 0 04:04 pts/0 00:00:00 grep --color=auto -i watchdogd

  • In general, or specifically for the watchdogd process? – Jeff Schaller Nov 29 '18 at 12:02
  • Specifically for watchdogd process. – Maks Nov 30 '18 at 9:08
  • Why do you wish to rename the watchdogd kernel thread? – fpmurphy Dec 3 '18 at 7:34
  • One of my own service is also having same name that's why i want to either rename or disable kernel's watchdogd. – Maks Dec 3 '18 at 11:01

It’s not a system service but a kernel thread. Documentation for the watchdog is in the kernel source documentation. I don’t think you can easily rename without recompiling your own kernel.

  • Is it possible to stop execution of this thread during startup ?? – Maks Dec 3 '18 at 11:03
