Thanks for reply. I have taken a thread dump at the time of query execution. I do not know the thread name so send the All threads. I have also send the logs so you can get idea.
Thread Dump All Stack Trace: https://drive.google.com/file/d/1N4rVXJoaAwNvPIY2aw57gKA9mb4vRTMR/view Solr 8.3 shard 1 log: https://drive.google.com/file/d/1h5d_eZfQvYET7JKzbNKZwhZ_RmaX7hWf/view Solr 8.3 shard 2 log: https://drive.google.com/file/d/19CRflzQ7n5BZBNaaC7EFszgzKKlPfIVl/view I have some questions regarding the thread dump - How can I know the my thread name from thread dump? can I get from the log? - When do I take a thread dump? on query execution or after query execution? Note: I got a thread name from log and checked in thread dump on query execution time and after query executed. Both time thread stack trace got different. If any other things are required then let me know I will send.

Please share the deepest thread stack. This might give a clue what's going on there.
