[Swift-user] Swift run: java.io.IOException: Unknown error 512

[lixi at uchicago.edu]

Hi,

I ran a workflow like this:
[lixi at communicado test]
$ /home/lixi/performancetest/4/cog/modules/vdsk/dist/vdsk-
svn/bin/swift -
sites.file ../sitesfile/SELECT1/sites2.0808062300.xml -
tc.file ../tc.data testworkflow.swift >0808062300.log 2>&1 &

During the execution, it stopped suddenly and the stdout and 
stderr are included 
in /home/lixi/performancetest/test/0808062300.log. It seems 
that it stopped due to "java.io.IOException: Unknown error 
512"

The log file is /home/lixi/performancetest/test/testworkflow-
20080806-2301-m1qbxjr3.log

[lixi at communicado test]$ tail -n 20 0808062300.log

Would you please tell me why such an error happened and what 
to do with it?

Thanks,
