Hi Forum
Well in my hunger for learning more - I’ve setup a little cluster at home, and would like to move my xwiki from the VM - to a kubernetes installation. - so absolutely still a newbie.
Created the xwiki instance on Kubernetes through the helm repo.
When I’m exporting the wiki from the old Wiki - its a file on 2.0 GiB (2,199,712,847 bytes) no issue shown while exporting the wiki.
But when trying to import it on my kubernetes - I’m uploading the file - and it uploads the file - but then crashing for some reason when its finished the upload, - that I havent figure out yet - just getting this notice in the bottom of the page
The Log shows this: 31-Jan-2024 08:01:02.220 WARNING [Thread-18] org.apache.catalina.loader.WebappClassLoaderBase.clearReferencesThreads The web application [ROOT] appears to have started a thread named [blocking-thread–p3-t1] but has failed to stop it. This is very likely to create a memory leak. Stack trace of thread:

org.jboss.threads.EnhancedQueueExecutor$ThreadBody.run(EnhancedQueueExecutor.java:1409)
java.base@17.0.10/java.lang.Thread.run(Unknown Source)
So its creating a memory leak
first thing - the storage for xwiki was only set for 500mb - so I can properly not get 2GB data to fit on this - resized the storage from 500mb to 4GB - and redeployed the Application - but still the same issue - As soon as it start importing the file - it’ll fail.

Is there any other way I can import my old created Wiki - so I dont have to manually recreate all 200pages/artices I’ve created through time
Its the same if I trying it on ingress or directly to the tcp port available.
