Interesting, I will take a look.

[blacklabelops]

I can verify this in Jira 7.6.0.

Still looking for a solution.

Simple solution:

• Disable caching

Wanted solution:

• Configurable: Not only size but move cached files outside image inside a Docker volume.

Can anybody provide their Tomcat cache configuration?

I am getting a massive amount of warnings about this as well.

How do I solve this?

Some say to increase this: https://docs.cloudbees.com/docs/cloudbees-ci-kb/latest/client-and-managed-masters/cache-warnings-in-catalina-logging

But that file is inside the container.
