Failed to process GML file


Our team uses FME and pipeline to process data together. We convert a large number of 3D model files into a GML file,then use pipeline to tile gml. During this process, pipeline occasionally reports the following errors, resulting in processing failure.So, what is the reason for this, or is there any solution.

Error: Invalid File
Filepath: F:\TransformServerWorkSpace\Temp\SWL_PIPE_LM_GML\SWL_PIPE_LM_GML\SWL_PIPE_LM_GML.gml
Details: unable to read data from file, Line 87043125, Column 169
