Bug Fixes

Fixed the following issues:

• Synchronizing data using StarRocks external tables encounters the error "commit and publish txn failed". The synchronization succeeds after a retry but the same copy of data is loaded twice. #25165
• RPC transmit resources are temporarily unavailable due to GC issues. #41636
• array_agg() in v2.5 processes NULLs in a different way than it does in v2.3. As a result, the query result is incorrect after an upgrade from v2.3 to v2.5. #42639
• The Sink Operator in a query unexpectedly exits, which causes BEs to crash. #38662
• Executing the DELETE command on an Aggregate table results in a race for accessing tablet metadata, which causes BEs to crash. #42174
• The MemTracker encounters the Use-After-Free issue during UDF calling, which causes BEs to crash. #41710
• The unnest() function does not support aliases. #42138
