My computer is getting really laggy with a sendmail process (it's using 10% memory and 20% CPU all the time). I tried the following:

  1. Stopping the service -> Futile. The service doesn't exist.
  2. Killing the process -> Useless. The process restarts itself.
  3. Removing the software -> Fatal. It tries to take 700MB along with it.
  4. Renaming the binary -> Works. But it's a temporary solution.

I'm trying to identify which process is making the call to the sendmail process. How can I find the culprit?

The distro is Fedora 30.

I use Fedora as well. I usually call pgrep -x process then find those processes listed with ps -A.

  • This is so intriguing... it says bash is being responsible for running this process... Commented Oct 23, 2019 at 4:48
  • The next step is an entirely different issue, but your answer helped immensely. Cool name. Commented Oct 23, 2019 at 4:52
  • Is it a system startup process? You can use pstree -or- ps -H -or- ps aux | grep sendmail -or- ps auxww | grep sendmail Let me play around a bit, see what I can find. You may want something deeper than I am thinking. Commented Oct 23, 2019 at 4:52
  • Thanks. This is the way bash is running the process /usr/bin/bash /usr/sbin/sendmail -FCronDaemon -i -odi -oem -oi -t -f root Commented Oct 23, 2019 at 4:56
  • I am not too familiar with that daemon. I usually find what I need with top in the terminal, then what I linked at first to determine what all it's coinciding with at that time. Do you have a beefy system, or it is truly slowing down your rig? On a side note, here is a process list I keep in my favorites; sorry I didn't link at first, I had to find it: link.
