There's nothing Keycloak specific in /metrics endpoint currently so this
issue comes from WildFly. I opened
https://issues.jboss.org/browse/WFLY-12504 to get input from the WildFly
team.

Hi guys,
can somebody of you share some insights regarding memory leaks when
scraping the /metrics endpoint on keycloak? A Jira Ticket already exists
https://issues.jboss.org/browse/KEYCLOAK-10880 for some time but there
seems to be no progress. As far as I can tell it seems to be related to
internal keycloak/wildfly service integration and is not related to jdk
versions/variants or means of deployment (bare,vm,container).
We'd love to use the new endpoints in order to integrate them in our
Grafana dashboards and are happy to provide more information. Apparently
7.0.0 is also affected. To reproduce the behaviour just issue a ton of GETs
on the metrics endpoint. The more you GET the faster it dies.
Thank you for any hints
Best
Daniel
