confirmatory testing

tested with https://github.com/opencloud-eu/opencloud-compose
COMPOSE_FILE=docker-compose.yml:traefik/opencloud.yml:idm/ldap-keycloak.yml:traefik/ldap-keycloak.yml:weboffice/collabora.yml:traefik/collabora.yml:search/tika.yml

docker memory limit is 16Gb

Steps:

• Upload folders containing a large number of text files: over 1 GB, more than 800 files
• wait until index is done
• rename folder

Actual:
4.0.3: a sharp increase in memory usage. In my case, over 8 GB ~60%
4.0.4 (patch version): moderate memory usage of about 2 GB ~ 13%
