ArcGIS not creating a buffer around a line

I'm trying to create a 150 meter, full, flat buffer around a line, but ArcGIS (both 9.3 and 10.0) does not create the whole buffer every time I run the buffer tool. The buffer tool itself finishes, but it only creates a very small polygon. The line is relatively complex - it was generated using Network Analyst's Create Service Area tool.

The buffer tool successfully creates the buffer when the distance is set to 135 meters, but any distance value larger than 135 fails. The 150 meter distance works fine when the round option is selected. If I make the buffer distance large (300 meters), the buffer is created successfully.

Does anyone have any insights about this problem?
