Hello,
Are you hazelcast registry?
if so, we encountered a similar problem in our prod environment. Especially
after we converted one of our popular app from cas to Oauth. Here is what
our config that made out cas stable, without restarting on a schedule
I am wondering if this is related
to https://github.com/apereo/cas/pull/5652. We have been discussing this
issue because myself and some others have experienced a slowdown due to the
merged pull request but the fix provided by the pull request is related to
fixing out-of-memory issues with
These exceptions will not help you. They are consequences. Check instead
the server startup log files. Your memory settings as sayed before.

Hi,
Please post the stack trace
Did you configurer the Jvm to generate a heap dump when out of memory
exception is encouraged ?
Is it about meta space ?
Best regards

Hi Team,
I have upgraded to CAS 6.3.7.4 to 6.6.9 recently and I'm facing java heap
memory error. In CAS 6.3.7.4 I didn't face such issues in prod environment.
When I upgraded to CAS 6.6.9 I had faced this issue thrice and I have
posted this in community and as per their feedback and as per the
Sathish,
Your async-backup-count and backup-count have non default values. Is it
possible these values are causing hazelcast to consume memory?
Try using default values to see if memory use improves.
You can monitor the JVM with JDK Misson Control or jConsole.
Ray
P.S. To keep your config
Hi Sathish
Did you check the port(5701) access and connectivity of hazelcast members?
you can set the hazelcast.log.level to debug for more details in log.

Hi Team,
Hazelcast is causing problem. Since we have 3 servers clustered. Earlier we
have tomcat memory of 512mb min and max. I posted in CAS community and they
suggested to increase memory by max 2gb. It is running fine for 12 days and
stopped showing heap memory issue. The following are
Hi Team,
Prod server stopped due to following issues. Kindly help. I'm facing heap
memory issue for long time :(
Exception: java.lang.OutOfMemoryError thrown from the
UncaughtExceptionHandler in thread
"hz.10.34.196.43.MetricsRegistry.thread-2"
Exception: java.lang.OutOfMemoryError thrown
Not sure why it's complaining about an IP address that's not in your
configuration. I wonder if it's picking up a second IP that's configured?
You could try setting this:
cas.ticket.registry.hazelcast.cluster.core.instance-name=localhost
Sathish,
I was not able to find recommended memory requirements in cas docs. This guide
has a suggestion
https://paulchauvet.github.io/deploying-cas/setting-up-the-environment/tomcat/systemd-service/
Memory is cheap, I would start at 2G. See tomcat docs to configure this.
Cas also has some
Earlier I was using CAS 6.3.7.4 at that time we had tomcat server minimum
512 and maximum 512 memory. But when I upgraded to 6.6.9 it is showing
heap *java.lang.OutOfMemoryError: Java heap space *when i deployed in
clustered servers. Can you provide more suggestions

Hi Team,
I'm upgrading CAS 6.3.7.4 to 6.6.9. The below properties I have added
for Hazelcast and Ticket Registry in upgraded version. I'm seeing this
error which is printed in logs often. Kindly check below properties and
guide me if any modification/addition/deletion of properties.

Hello try to give more memory (set the Xmx jvm property ) 512 is very low
