MariaDB Error 1258: ZLIB Decompression Buffer Error
Description
Error 1258 indicates a failure during data decompression using the ZLIB library, specifically that the output buffer allocated for the uncompressed data was insufficient. This typically occurs when MariaDB attempts to process compressed data (e.g., from compressed columns, replication streams, or network packets) and either the compressed data is corrupt, or the metadata specifying its original length is incorrect.
Error Message
ZLIB: Not enough room in the output buffer (probably, length of uncompressed data was corrupted)
Known Causes
3 known causesCorrupt Compressed Data
The input data intended for decompression is damaged or malformed, preventing ZLIB from correctly calculating the required output buffer size.
Invalid Uncompressed Length Metadata
The metadata associated with the compressed data, which specifies its original uncompressed length, is incorrect or missing, leading to an undersized buffer allocation.
Insufficient Buffer Allocation
The system or MariaDB failed to allocate an adequately sized buffer for the decompressed data, even if the input data was valid and its metadata correct.
