Growing .core file extension in root

Questions
#1

Hi to all,
simple question, but not form me :stuck_out_tongue:
what are these files with the extension .corexxxx (number) that I see creating in the n8n installation root and taking up a lot of space? I am attaching a screenshoot, I hope someone will answer me, I am trying to do some cleanup on the server and I would like to understand what kind of files they are, thanks.

Hey @Giorgio,

I have not seen one of those before, What version of n8n is it, how is it installed / running and what database is being used?

Thank you for you reply, so, my n8n version is the 0.204.0 is installed with npm and pm2 (continuous working) and have mysql database. I do not understand what kind of file are this :face_with_spiral_eyes:

Hey @Giorgio,

That is perfect so a core.x file is a PM2 core dump file, It probably means at some point it crashed and that is a debug file.

I would say you should be safe to just delete those files but check the PM2 docs first to make sure.

core.xxxx files are often Core-dump files.
Since n8n is not compiled to a native binary, these files are likely coming from another process.

Can you please look online for instruction on how to disable core dump for your operating system, and try that?
