Thirunarayanan Balathandayuthapani 2ef1baa75f Bug #24793413 LOG PARSING BUFFER OVERFLOW ... Problem: ======== During checkpoint, we are writing all MLOG_FILE_NAME records in one mtr and parse buffer can't be processed till MLOG_MULTI_REC_END. Eventually parse buffer exceeds the RECV_PARSING_BUF_SIZE and eventually it overflows. Fix: === 1) Break the large mtr if it exceeds LOG_CHECKPOINT_FREE_PER_THREAD into multiple mtr during checkpoint. 2) Move the parsing buffer if we are encountering only MLOG_FILE_NAME records. So that it will never exceed the RECV_PARSING_BUF_SIZE.
