db_stress gets stuck

To Reproduce
Steps to reproduce the behavior:

  1. rm -rf /tmp/rocksdb_crashtest_*

  2. mkdir /tmp/rocksdb_crashtest_blackboxod86ddmf

  3. mkdir /tmp/rocksdb_crashtest_expected_vy0z2l_r

  4. ./db_stress --acquire_snapshot_one_in=10000 --adaptive_readahead=1 --allow_concurrent_memtable_write=0 --allow_data_in_errors=True --allow_wbm_stalls=1 --async_io=0 --avoid_flush_during_recovery=1 --avoid_unnecessary_blocking_io=1 --backup_max_size=104857600 --backup_one_in=100000 --batch_protection_bytes_per_key=0 --block_size=16384 --bloom_bits=1.3037923446511857 --bottommost_compression_type=none --bytes_per_sync=0 --cache_index_and_filter_blocks=0 --cache_size=8388608 --cache_type=lru_cache --charge_compression_dictionary_building_buffer=1 --charge_file_metadata=1 --charge_filter_construction=0 --charge_table_reader=0 --checkpoint_one_in=0 --checksum_type=kxxHash --clear_column_family_one_in=0 --compact_files_one_in=1000000 --compact_range_one_in=1000000 --compaction_pri=0 --compaction_ttl=1000 --compare_full_db_state_snapshot=0 --compression_max_dict_buffer_bytes=511 --compression_max_dict_bytes=16384 --compression_parallel_threads=1 --compression_type=xpress --compression_use_zstd_dict_trainer=0 --compression_zstd_max_train_bytes=0 --continuous_verification_interval=0 --create_timestamped_snapshot_one_in=20 --customopspercent=0 --data_block_index_type=0 --db=/tmp/rocksdb_crashtest_blackboxod86ddmf --db_write_buffer_size=8388608 --delpercent=19 --delrangepercent=0 --destroy_db_initially=0 --detect_filter_construct_corruption=0 --disable_wal=0 --enable_compaction_filter=0 --enable_pipelined_write=0 --expected_values_dir=/tmp/rocksdb_crashtest_expected_vy0z2l_r --fail_if_options_file_error=0 --fifo_allow_compaction=0 --file_checksum_impl=crc32c --flush_one_in=1000000 --format_version=5 --get_current_wal_file_one_in=0 --get_live_files_one_in=100000 --get_property_one_in=1000000 --get_sorted_wal_files_one_in=0 --index_block_restart_interval=4 --index_type=0 --ingest_external_file_one_in=0 --initial_auto_readahead_size=16384 --initiate_wbm_flushes=0 --iterpercent=7 --key_len_percent_dist=100 --level_compaction_dynamic_level_bytes=True --lock_wal_one_in=1000000 --long_running_snapshots=0 --manual_wal_flush_one_in=1000 --mark_for_compaction_one_file_in=10 --max_auto_readahead_size=16384 --max_background_compactions=20 --max_bytes_for_level_base=10485760 --max_key=102400 --max_key_len=1 --max_manifest_file_size=1073741824 --max_write_batch_group_size_bytes=64 --max_write_buffer_number=3 --max_write_buffer_size_to_maintain=1048576 --memtable_prefix_bloom_size_ratio=0 --memtable_protection_bytes_per_key=2 --memtable_whole_key_filtering=0 --memtablerep=skip_list --min_write_buffer_number_to_merge=2 --mmap_read=1 --mock_direct_io=False --nooverwritepercent=30 --num_file_reads_for_auto_readahead=2 --num_iterations=25 --open_files=-1 --open_metadata_write_fault_one_in=0 --open_read_fault_one_in=0 --open_write_fault_one_in=0 --ops_per_thread=100000000 --optimize_filters_for_memory=1 --paranoid_file_checks=1 --partition_filters=0 --partition_pinning=3 --pause_background_one_in=1000000 --periodic_compaction_seconds=10 --pinning_policy=speedb_scoped_pinning_policy --prefix_size=-1 --prefixpercent=0 --prepopulate_block_cache=1 --preserve_internal_time_seconds=36000 --progress_reports=0 --read_fault_one_in=32 --readahead_size=0 --readpercent=28 --recycle_log_file_num=0 --reopen=0 --ribbon_starting_level=999 --secondary_cache_fault_one_in=32 --secondary_cache_uri= --seed=3618268266 --set_options_one_in=10000 --snapshot_hold_ops=100000 --sst_file_manager_bytes_per_sec=104857600 --sst_file_manager_bytes_per_truncate=1048576 --start_delay_percent=22 --stats_dump_period_sec=600 --subcompactions=2 --sync=0 --sync_fault_injection=1 --sync_wal_one_in=100000 --target_file_size_base=2097152 --target_file_size_multiplier=2 --test_batches_snapshots=0 --top_level_index_pinning=3 --txn_write_policy=0 --unordered_write=0 --unpartitioned_pinning=3 --use_direct_io_for_flush_and_compaction=0 --use_direct_reads=0 --use_dynamic_delay=1 --use_full_merge_v1=False --use_get_entity=1 --use_merge=1 --use_multiget=1 --use_put_entity_one_in=0 --use_txn=1 --user_timestamp_size=0 --value_size_mult=32 --verify_before_write=False --verify_checksum=1 --verify_checksum_one_in=1000000 --verify_db_one_in=100000 --verify_sst_unique_id_in_manifest=1 --wal_bytes_per_sync=0 --wal_compression=none --write_buffer_size=1073741824 --write_dbid_to_manifest=1 --writepercent=46
