Keep getting core files

I repeatedly get a message about core files, asking for me to send these core dumps. 

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 Once the core files have been archived and attached to the ticket, they may be removed by running the following command in shell: 'rm /var/db/system/cores/*'.

Not sure what is going on.  But doing as asked.
