python3.8 core dump TrueNAS-12.0-U2.1

I recently encountered a situation where the WebUI for both of my TrueNAS machine became unavalible.  Almost as if the system was offline or had rebooted, but It appears that only the webfrontend was inaccesssible, as I was able to ssh into my machine and restart the WebUI.

I ran the following

service middlewared restart
service nginx restart

I believe restarting middlewared resolved the issue, however I recieved a notification to the following:

"The following system core files were found: python3.8.core. 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 Once the core files have been archived and attached to the ticket, they may be removed by running the following command in shell: 'rm /var/db/system/cores/*'."

You can wget a tar of the core here:
 

wget https://danksquad.org/python3.8.core.tar

Please let me know when it is no longer needed, I would like to remove it from my web server
