ArcGIS Server 10.1 a geoprocessing service failure under Redhat ELS 6.3

Discussion created by yongtaol on Aug 23, 2012
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.
