small like 4096. You need to set it to 65535. in your

Subject: 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
