Based on the stack trace you provided, the StarRocks Backend (BE) is crashing with a

SIGFPE

(Floating Point Exception) inside the BitShuffle decompression logic (

bshuf_default_block_size_avx2

) during compaction (

TabletUpdates::_do_compaction

). Root Cause Analysis A

SIGFPE

at this specific location typically indicates a division-by-zero error within the BitShuffle library. This happens when the library attempts to calculate the processing block size by dividing a target buffer size by the element size of the column data. If the element size passed to the decoder is 0, the process crashes. This can occur due to: 1. Metadata Corruption: The segment file's footer or the column metadata on disk has been corrupted, leading the BE to read an element size of 0. 2. Schema/Type Inconsistency: A bug in a specific StarRocks version where certain data types (often complex types like

ARRAY

or variable-length types) are handled incorrectly during the compaction merge phase. 3. Instruction Set Issues: While less likely for

SIGFPE

, if the environment (e.g., Docker/VM) incorrectly reports AVX2 support or has an incompatible CPU, SIMD-optimized math libraries can sometimes behave unpredictably. Recommended Steps 1. Identify the problematic Tablet Check the

<http://be.INFO|be.INFO>

or

be.out

log file immediately preceding the crash. Look for a line similar to:

[tablet_updates.cpp:...] start to do compaction for tablet: <TABLET_ID>

Identifying the

TABLET_ID

allows you to pinpoint which table and data partition are causing the crash. 2. Check for Metadata Inconsistency Once you have the

TABLET_ID

, run the following in your MySQL client:

sql
ADMIN SHOW REPLICA STATUS FROM <table_name> WHERE TabletId = <TABLET_ID>;
-- Verify if the replica is healthy and check its version.

You can also try to force a check on the tablet:

sql
ADMIN CHECK TABLET (<TABLET_ID>);

3. Workaround: Disable BitShuffle (If applicable) If this is a recurring issue on a specific table and you can recreate it, try using a different encoding (like

PLAIN

or

LZ4

without BitShuffle) for numeric columns. BitShuffle is often the default for integers/floats. 4. Version & Environment * Upgrade: If you are on an older version (e.g., 2.x or early 3.x), this might be a known bug in the storage engine's metadata handling. Check if there is a newer patch release. * CPU Compatibility: Ensure your BE nodes are running on CPUs that fully support AVX2. If you are mixing different CPU architectures in one cluster, this is not recommended. Next steps: If the crash persists after identifying and repairing the problematic tablet, please provide your StarRocks version (

SELECT current_version();

) and the table schema to help narrow down if this is a specific data-type bug.
