I need to freeup some CPU/RAM usage and thinking to stop some unnecessary services if not effect on zammad functionality. Need to know do you confirm this services
I would be appriciate for any other advise.
Well with Java you have one of the hungriest proccesses on a Zammad instance.
However, I’m afraid it’s required for elasticsearch to be running. (Java is a elasticsearch dependency).
Nobody can answer this question in terms of your instance setup.
If you send mails via sendmail on that host, you shouldn’t remove postfix. Postfix is a mail server / mta that can send mails for you. Again, that’s something probably only you can tell.
