shuwenwei opened a new pull request, #11054:
URL: https://github.com/apache/iotdb/pull/11054

   ## Description
   https://github.com/apache/iotdb/pull/11046
   When FastCompaction deserializes a overlapped Chunk into the Page queue, the ByteBuffer.get() method is called from the Chunk's Buffer to copy the data of each Page. After copy, the Page is wrapped into a PageElement and put into the pageQueue, but the timeChunk and valueChunks are passed into a new instance of AlignedChunkReader, which causes the clearChunks method to be called at the end of the method is not effective. The reference of each Chunk is still held by AlignedChunkReader and cannot be released. At this time, there is 2 times the chunk size of data in the memory.
   ## Fix
   Release chunk data buffer after copy page data from it.
