Recently, I installed a ArcGIS server 10.1 Linux version to a Redhat ELS 6.3 X64 and a windows version to Win 7 Pro. Installation went smoothly, and I can also deploy my python scripts which run perfectly under server 10.1 windows OS. I deployed the same scripts to 10.1 Linux version. Most of script tools can run perfect, only one contains "arcpy.MakeRouteEventLayer_lr" screwed me up as following errors: The error showed in Result window: Could not service request, java.rmi.UnmarshalException: Error unmarshaling return header; nested exception is: java.io.EOFException. The error showed in server log: The containing process for 'test' job 'jced20217a59341f88b8da8e12709f895' has crashed. test.GPServer failed to process request. The issue seems a server object serializing and deserializing problem caused by the server. Is this an ESRI bug for server 10.1 Linux version. Thanks in advance. Yongtao
