any issues with MailScanner and locked pages?

I'm trying to track down an issue on my VPS.

For some reason, every 7-10 days or so the server crashes because the
container exceeds the allowed number of lockedpages.

MailScanner and MySQL are the two processes that use the most memory on
my system (CentOS 7) by far, so I'm investigating each as much as I can
to try to identify why this is happening.

The server doesn't run out of memory. On the contrary, usually about
half the memory remains unallocated when these events occur.

Has anyone run into any issues with MailScanner locking too many pages
in memory?
