Ram usage

[Damiano Perri]

Is it normal that the amount of ram used continues to increase over time?
Yesterday it had reached 756MB and I had to restart it because I was afraid it would crash my server.

This is my docker-compose files:

version: '3'
services:
mailserver:
image: analogic/poste.io
container_name: mailserver
restart: always
ports:
- "25:25"
environment:
- LETSENCRYPT_EMAIL=[e-mail]
- LETSENCRYPT_HOST=mysuddomain.domain.com
- VIRTUAL_HOST=mysuddomain.domain.com
- HTTPS=OFF
- VIRTUAL_PORT=80
- DISABLE_CLAMAV=TRUE
- DISABLE_ROUNDCUBE=TRUE
- DISABLE_RSPAMD=TRUE
volumes:
- ./data/mailserver:/data
networks:
default:
external:
name: nginx-proxy

‌

The emails and the virtualhosts works well, my only question is whether it is normal for the used ram to grow over time.
Does this docker need to be restarted periodically?

Thank you

From reading other posts, it looks like there’s a memory leak somewhere, most probably in the Poste.IO code that manages the Haraka or one of it’s Javascript plugins.
