[Memory] Swap is being filled in

[VladislavKara]

Hello everyone, I have a question, about a month ago I received a memory swap error message on my Linux mail server, because dbmail-lmtp and dbmail-imap store information in swap, I restarted these services and increased the swap space, but recently I received an error message again, and I think that this is not good, I don't want to constantly restart email services, and I hope you can help me with this.

P.S. I don't see any errors in the logs that would be related to the problem of sending or saving mail.

Have you any ideas?

Thank you in advance

Memory leaks are a known issue. Although the majority have been fixed, work is ongoing to track down and fix them.
The current recommended fix is to monitor memory usage and restart any service that goes over your target memory usage.
