Core files found: /usr/bin/rrdcached - What the heck is that?

[trebong]

Hello everyone,

I hope, this is the correct subforum.

I have just received an alert by e-mail from my server (see below). My English is not the best, so I have therefore had the text translated. I understand the sentences now, but I still don't understand the content. (And that's probably not because of the translation ;) )

What is this mistake? Where does it come from? Why is that?

What kind of programme is /usr/bin/rrdcached? Who is ixsystems.com? Is this serious? Why should I report a bug there and not here in the forum? Should I run the shell command or not?


Core files for the following executables were found: /usr/bin/rrdcached (Wed Nov 15 15:45:51 2023). Please create a ticket at https://jira.ixsystems.com/ and attach the relevant core files along with a system debug. Once the core files have been archived and attached to the ticket, they may be removed by running the following command in shell: 'rm /var/db/system/cores/*'


And I got this by accident on the terminal:
