Network Analyst Trimm Service Areas Problem

Hi all,

I'm working on creating service areas for a public transport station layer. There is this "Trimm" function which can be enabled. Using the following settings, trimming polygons functions:

- generalized
- merge by break value
- overlap type: disks
- default breaks: 300 seconds (from cost settings)

However, if changing settings to:
- detailled
- 60, 120, 180, 240, 300 seconds (from cost settings)

the trimming process seems to hang - there is no process after 50% and no further reaction of ArcGIS 9.3.1.

Is there any known bug or a way how I can avoid the problem?

Thanks for any suggestions,
