In the wso2carbon.log , the following stacktrace keeps on appearing.I am using combination of WSO2 identity server and WSO2 API Manager togother.And now configured custom domain names for both of them. But now the error is being printed out. Is it like should i update the custom domain name somewhere instead of localhost for JMS?

What could be the reason for this?
As mentioned in the error itself, you should update repository/conf/jndi.properties

I have setup wso2am-4.0.0 and I have configured readonly ldap as the primary userstore.
After changing to readonly ldap, the following error is seen in the logs and it is recurring forever. The API calls also seem to be failing due to it.

Are there anything wrong in the deployment.toml?
In APIM active-active setup, each node is publishing throttling data to itself and to the other node. When you stop the other node, it can't publish the throttling data to the other node. Hence you see connection refused errors and this is expected. No harm having these error logs. It will recover when the other node is started. If you look at the deployment.toml, can find the other node details under the throttling configurations.

Looks like zookeeper's not running.
See the quickstart - you need to start the zookeeper and kafka servers.
