Collabora Kit Process Killed on Large File Open (>1GB)

User Support
1

Hi all,

I’m running Collabora Online in Docker, integrated with Nextcloud. Everything works great for small to medium documents. But when I try to open large files (>1GB)*— like big .pptx or .docx files — the document fails to load, and the Collabora Kit process gets killed with status 9. Can I know how to fix this issue? Thank you.

hii @vasista welcome to collabora online forum

I would suggest if you can checkout this thread Is there a limit on the size of documents loaded by Collaborator Online? - #2 by Tex

This will help with your case to increase the limit for large documents

Thanks
Darshan

Hi @darshan, Thanks for the reply. I have changed it to 0.

cool@collabora:/$ cat /etc/coolwsd/coolwsd.xml | grep limit_load_secs
        <limit_load_secs desc="Maximum number of seconds to wait for a document load to succeed. 0 for unlimited." type="uint" default="100">0</limit_load_secs>

and I have restarted the container, and I still have the issue. Is there a special command I need to execute to take these changes or restart is sufficient?

Below is the error:

Thanks for the detailed follow-up. You’re doing the right thing modifying <limit_load_secs> to 0, but the log clearly says:

per_document.limit_load_secs set to 5s secs

This means your change to coolwsd.xml is not taking effect, likely because the Docker image isn’t using that file inside the container.

Can you please first check your docker config and confirm that the changes is taking place or not

Hi. Sorry, but I am not sure, on how to do that. Can I know how to check, if the container is actually using this coolwsd.xml?

I also see this in the logs which might say, I am setting it to 0, and it is taking that value and for some reason it is being overriden.

I would suggest to checkout our SDK documentation for configuration settings Configuration — SDK https://sdk.collaboraonline.com/ documentation

Hi @darshan, Thanks for the docs. I have changed my docker compose with extra parameters for limit_load_secs to zero.

- "extra_params=--o:ssl.enable=false  --o:ssl.termination=true --o:per_document.limit_load_secs=0"

and I checked the docker logs, if this value is taken and indeed it is

docker logs collabora |grep limit_load
	per_document.limit_load_secs: 0

and I still have the errors and the override which I was mentioning. I have attached the logs below.

Also, I tried the other way around, and Increased the limit_load_secs value to 10000

and I still have the same errors.

Sorry, if it is too much information dumping.
