Hello All,

I’m trying to update/change keycloak log level when my keycloak container is running.  
I’m getting the below error, please provide your guidance on the same.

$ /opt/bitnami/keycloak/bin/kc.sh start --log-level=DEBUG  
Appending additional Java properties to JAVA\_OPTS: ‘-Djdk.security.allowNonCaAnchor=true’  
ERROR: transport error 202: bind failed: Address already in use  
ERROR: JDWP Transport dt\_socket failed to initialize, TRANSPORT\_INIT(510)  
JDWP exit error AGENT\_ERROR\_TRANSPORT\_INIT(197): No transports initialized [src/jdk.jdwp.agent/share/native/libjdwp/debugInit.c:744]

Hi @sathyavathy1 ,  
Since the loglevel is a command line argument at startup it can’t be changed during runtime.  
I would run Keycloak with more than 1 replica (e.g. with docker compose) and then do a rolling update  
of the containers with new loglevels.  
That way you can achieve changes without a downtime to your Keycloak Service.
