This is one of my first posts, so hoping it’s the right place.
I was trying to figure out if it’s possible to get support from Red Hat for example, but let me try this
We are running Keycloak 11.0.3 in Azure AKS. A 3-node setup using the Azure PostgreSQL database version 11.
We currently have 373 realms. We are hosting customer environments, and each environment has it’s own realm.
We are seeing that performance at the moment is pretty bad. Simply loading all realms when logging in takes 20-30 seconds, and also creating new realms takes longer and longer, and sometimes we get timeouts.
During approximately 1 month, we see that memory usage is growing, GC count and GC time grows a lot (!) and then we have to restart the KC nodes (pods).
I am not an expert on Keycloak or PostgreSQL at all, but I am hoping that someone can help and suggest on what to do to troubleshoot this.
Are we using KC in bad way?
Are there known issues with KC v11?
How do I check PostgreSQL to see if it’s a database problem?
Thanks in advance,
