Shiva,
What version of Ignite do you use and do you have security configured in the
cluster?
There was a bug in Ignite before version 2.7, that has similar symptoms:
https://issues.apache.org/jira/browse/IGNITE-7624
It’s fixed under the following ticket:
https://issues.apache.org/jira/browse/IGNITE-9535
Try updating to the latest version of Ignite and see if the issue is resolved
there.
If this is not your case, then please collect thread dumps from all nodes and
share them in this thread. Logs will also be useful.
Please don’t add it to the message body, use attachment.
