Cache keeps growing. Cache expiration in onlyoffice docker with admin panel

[knurd75]

Document Server:
Type: Enterprise Edition
Version: 9.1.0.168

Dear helpful people of this community,

As with some other threads on this site, our cache does not clean up properly.
We have files from years ago, but also right now not all files in the cache vanish in 24h as they should. We are slowly running out of space.

It is a docker install without much costumization. Onlyoffice is used with Nextcloud.
It runs on an up to date debian bookworm. Onlyoffice works fine, according to user feedback, but the cache keeps growing bigger.

Here the docker-compose.yml

version: ‘2’
services:
onlyoffice:
container_name: onlyoffice-documentserver-ee
image: onlyoffice/documentserver-ee
environment:
- NGINX_WORKER_PROCESSES=16

- JWT_IN_BODY=true

stdin_open: true

Cache files are not cleared

Hello, Our OnlyOffice server is running version 8.3.1-25 on debian 12 We have issues with cache files clearing, some older than 1 day are not cleared automatically. The issue seems similar to this post (we are not running OnlyOffice on Docker): Cache files aren't cleared The default.json file seems to be configured correctly, and the database also appears to be fine. We had to manually clear the cache files about a week and a half ago. I attached today screenshots of folder “data” and “forg…

and

Cache files aren't cleared

Running onlyoffice/documentserver (version 6.3.1.32) in docker. Installation as described in Installing ONLYOFFICE Docs for Docker on a local server - ONLYOFFICE As written there: running container with option -v /app/onlyoffice/DocumentServer/lib:/var/lib/onlyoffice So all cache files are stored outside container. It looks like these cached files are not cleared/deleted (completely). There are a lot of files older than 1 day. In default.json I use default settings under “expire”: for files…

Especially

Docker - relation between default.json and local.json

Yes, we do not recommend it. You have to keep in mind that config file can be changed due to update process. So, for container deploying you can use environment variables. But there’s a workaround solution for parameters which cannot be set via environment. As we know default.json file can be overwritten during an update and the changes will be lost. If you wish to avoid that, you can create a file named local-production-linux.json in the same folder and paste the required parameters from de…

…but I think all these approaches to configuring cache expiration in docker are superseded by the admin panel. I could not get local-production-linux.json to work for me, but the admin panel works.

I have set the log level to debug through the admin-panel and am now seeing, that my changes through the admin panel are respected by the docker. I have changed the
Cache Cleanup Cron Expression to 00 */10 * * * * and the Files Removed At Once to 899 just to see if in our rather large installation the default 100 Files Removed At Once were the reason not 1all the files were deleted.

In the Log files I see that files are being removed.

zfgrep “end: removedCount” out.lo*|less

shows me many lines like:

out.log:[2025-11-19T09:44:17.223] [INFO] [localhost] [docId] [userId] nodeJS - checkFileExpire end: removedCount = 39
out.log:[2025-11-19T09:54:17.321] [INFO] [localhost] [docId] [userId] nodeJS - checkFileExpire end: removedCount = 35

When we shut down the server we always religiously use the

docker exec onlyoffice-documentserver-ee documentserver-prepare4shutdown.sh

My questions:

• What further information do you need to possibly help me get to the bottom of this?
• What should I do with the year old files in the cache that are probably no longer in the database?

kind regards,
Andreas

Hello @knurd75
Sorry for the late reply.
Please let us know your Nextcloud and the connector app just in case.
Now about the situation. Please go inside the container (docker exec -it ID_of_container bash) and check size of folders here: cd /var/lib/onlyoffice/documentserver/App_Data/cache/files > ls -lah

Also go to the Admin panel and show us your settings for Expiration tab (both Garbage Collection and Session Management). Additionally, are the any files in Forgotten Files tab?
Also, if you can share entire Document server logs folder, it would be helpful as well.

One more thing. I’ve noticed you’re using onlyoffice/documentserver-ee. If you have commercial license, you can contact colleagues of mine at https://helpdesk.onlyoffice.com/hc/en-us to get prompt replies.
