Custom RSS Feed causing memory issue

[suhass86991778]

A custom RSS feed gets regenerated with a scheduler which runs everyday to fetch updates of latest content. It does not use a workflow for any generation. These are simple xml files with custom rss template defined, saved at /content/*/Feed.xml. The scheduler runs on Publish instances. These xml files are getting saved at /mnt/tmp directory which is causing disk space issues on publish, where, for a certain period, the size of /mnt/tmp is going beyond 20 GB. How/Why are these xml files getting saved at /mnt/tmp directory? AEM v6.3.2.2

In your thread title - you said this is a custom RSS feed. Is this a custom service generating these files?

[suhass86991778]

Yes, it is a custom service that was built to generate these files.

[smacdonald2008]

Is your custom service persisting the XML files at the specified JCR location?

[suhass86991778]

Yes, the path to JCR location is pre-defined, when the scheduler runs, the saved xml gets updated along with jcr:lastModified property, filename+".xml/jcr:content/renditions/original/jcr:content"

[Jörg_Hoh · Accepted solution]

can you check what directory is used as directory for temporary files? It's either specified by the system property "java.io.tmpdir" or by environment variables.

I think that these RSS files are created initially on disk in temporary files and then copied into the repository, but not properly closed on the filesystem.

Thanks.

java -XshowSettings showed the java.io.tmpdir path

My service was creating binary files in tmp dir and later adding it to the node. But I forgot to delete the tmp files after.
