S12003

Error Code

S12003

Error Message

Failed to serialize level file {BlockType}: filepath_=<xxx>. Please check your disk or file system. RefId: S12003

Failed to deserialize level file {BlockType}: filepath_=<xxx>. Please check your disk or file system. RefId: S12003

Probable Causes

These errors occur when there is a failure in writing to a file during the flush (serialization) or merge (deserialization) process. The system will log the error and roll back the flush/merge operation.

Deserialization failures may be caused by:

Compatibility issues, such as using an older version server to read data written by a newer version server.
Disk or file system failures.
Corruption of level files.

Solutions

Check if the disk is full or damaged.
Check if there are any issues with the file system.
