My self hosted XWiki in a docker container runs stable over a couple of weeks now. But just a smaller question:
With 3 created wikis the docker process on server constantly consumes nearly 6 GB memory and there is not so much left for the other processes.
There are just a few documents and just 3 users working sporadically with the wikis.
Is this normal?
Is there a way to control it?
I use the standard settings for the Java heap (~ 1 GB I believe)
Hi. No it’s not normal, see https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Performances/#HMemory
Hi Thanks for the very quick answer and the link (I have found before).
Is there any strategy then to find out what’s wrong?
a ‘top’ inside the container shows:

means the java process is using 5172804 and therefore 27.8% of memory.
