Cannot start service [ADM.Default] in client mode
Just upgraded from Pega 7.3.1 to 24.1.1 but my pod seems to be stuck in a continuous reboot cycle. I am wondering if this error is the cause:
ERROR BWQ4WC1WRFCAY0INFOZKG30SX3IY1K4WLA - Cannot start service [ADM.Default] in client mode com.pega.dsm.dnode.api.dds.service.SessionNotAvailableException: Unable to obtain session. Cassandra hasn't been started or is unavailable ....
Caused by: java.lang.NullPointerException at com.pega.dsm.dnode.api.dds.service.v4.CassandraSessionCache.createNewSession(CassandraSessionCache.java:218) ~[d-node.jar:?] at com.pega.dsm.dnode.api.dds.service.v4.CassandraSessionCache.getSession(CassandraSessionCache.java:164) ~[d-node.jar:?]
....
I'd prefer to disable ADM since we will not be using it, but I'd be happy to just get rid of the error any way possible.

@JohnF17280011The error you are encountering, which states that 'Cassandra hasn't been started or is unavailable,' is indeed a common cause for issues like continuous reboot cycles after an upgrade. This error indicates that the ADM service is unable to obtain a session due to Cassandra not being available. In your case, it seems that the configuration may not be set up correctly for Cassandra, or it may not be running at all. You might have to check the status of your Cassandra service and ensure that it is properly configured and started. Additionally, if you are using embedded Cassandra, note that it is no longer supported in the latest versions, which could also lead to such issues.

@thulg If Cassandra is only needed for ADM, I'd prefer to turn ADM off if that's possible. We really don't have a need for ADM. At the moment, Cassandra is set up as is embedded.

@JohnF17280011 Faced same issue while upgrading from Pega 23.1.1 to Pega 24.1.1. Pega ADM Services are not required in our project.
Disabling Job pyInitADMModelConfigurations from Admin Studio has resolved the issue
