I'm trying to deploy the test program "worker", and I follow the instructions from BOINC website: http://boinc.berkeley.edu/trac/wiki/WrapperApp, I do everything as same as its description. Finally, I connect my BOINC server via BOINC client, version is 6.4.4, the error information is below:
14-Mar-2009 00:19:17 [test] [error] Can't rename output file worker_nodelete_0_0 to projects/10.141.1.202_test/worker_nodelete_0_0: Error -1;
14-Mar-2009 00:19:17 [test] Computation for task worker_nodelete_0 finished;
14-Mar-2009 00:19:17 [test] Output file worker_nodelete_0_0 for task worker_nodelete_0 absent;
14-Mar-2009 00:19:17 [test] Output file worker_nodelete_0_1 for task worker_nodelete_0 absent;

Does anyone know what hells going on? I tried replace the test program "worker" to my own program, but the error information is same. And I also found that if I remove the label "<copy_file/>" in output template file "worker_result", the error "Can't rename..." disappeared, but the output "absent" error still exists.

I read the BOINC document carefully and can't find the root cause. If I use "wrapper" at standalone mode, everything is ok, so the "wrapper" program is correct. I also tried to disable the file deleter daemon in config.xml file, and then, I can see the relative files in slot folder on client machine, but after a very short time (less than 1 second), those files are gone.

Does anyone make that test application successfully running or give me some help?

Thank you!
