Comment 11 for bug 1572608

I'm pretty sure it's not a RAM thing. The system I encountered the CPU soft lockup on has 192GB of RAM, and Zabbix shows it as mostly being free when the problem occurred.

As an aside, Victor, are you sure this is the same problem you're having? Looking at your error log, it appears to be something else? In the release notes for the Badlock fixes there were a few new options in smb.conf that can affect authentication.
