Question about Alfresco Down in Alfresco 6.2.0 (using FTP)

[ujkim]

We installed the Alfresco 6.2.0-ga version and added the FTP configuration information below to build it.

# Dockerfile
FROM alfresco/alfresco-content-repository-community:6.2.0-ga
EXPOSE 21 2333-2433

# Docker-compose file
(JAVA_OPTS)
-Dftp.port=21
-Dftp.enabled=true
-Dftp.dataPortFrom=2333
-Dftp.dataPortTo=2433
-Dftp.externalAddress=x.x.x.x
(ports)
- 21:21
- 2333-2433:2333-2433

We completed the setup and restarted.

And then, We are uploading data previously managed separately via FTP. 

In the process, Alfresco died.

When I checked the log, the following issue occurred.

(JLAN keeps getting FileExistsException Errors and seems to be dead due to memory problems.

Why this errors invoked?

Can I get some reason?

Thank you for good service.

It could likely be a memory issue, check the memory allocated to containers. Minimum 8 GB memory is required.

Use this command to see the stats:

docker stats

Check how much memory you have allocated to docker. That is shared between all the containers.

You can use this command to provide resources to docker:

docker run --memory 8g --cpus 2

If you are on windows, check this for docker desktop

if you are on mac, check this for docker desktop
