Hii [~aratnofsky] ,
We are getting 2 errors on all nodes. After these errors we see the merkle tree
errors. Please help in the resolution.

> Issue with Merkle Tree Creation and Parent Repair Session Failure
> -----------------------------------------------------------------
>
> Key: CASSANDRA-20348
> URL: https://issues.apache.org/jira/browse/CASSANDRA-20348
> Project: Apache Cassandra
> Issue Type: Bug
> Reporter: Aayush Gupta
> Priority: Normal
>
> We encountered an error while attempting to validate a repair session on our
> Cassandra cluster. The following issues were observed:
> * The validation failed during the creation of a Merkle tree for the repair
> session with ID {{a36dbed0-d787-11ef-84a0-59e4de22a9ca}} on the
> {{mailbox/messages_by_id}} table. Several ranges of SSTables were involved in
> the failure, and the logs indicate that the session could not be successfully
> validated due to issues with these SSTables.
> * The logs also show a failure in the parent repair session with ID
> {{{}a3695200-d787-11ef-84a0-59e4de22a9ca{}}}. The error traceback reveals
> that the {{ActiveRepairService}} could not retrieve the parent repair
> session, leading to the failure of the repair process. This caused further
> issues with repair message handling in the system.
> * The CassandraDaemon logs indicate that the error was related to an invalid
> or incomplete parent repair session, which was being handled by the
> {{{}RepairMessageVerbHandler{}}}. The repair operation failed, and the system
> attempted to remove the parent repair session, but was unable to proceed
> successfully.
> {*}Logs{*}:
> # The validation failed due to the inability to create a Merkle tree for a
> set of SSTables, and the parent repair session was marked as failed.
> # The {{RepairMessageVerbHandler}} encountered an exception, leading to the
> failure of the repair process, as seen in the attached stack traces.
> {*}Request{*}: We would appreciate assistance in understanding the cause of
> this failure, as well as any recommendations for resolving it. Specifically,
> any guidance on recovering the parent repair session or resolving issues with
> the Merkle tree creation would be helpful.
