Hello guys,

I try to run my BOINC project and test it with example_app uppercase and wrapper, but the event log always gives me error messages like output file absent.

and also, i cannot find stderr files on host and client, on client side the stderr was removed after the task was finished, even though output files are absent.

and when i double click wrapper direct under boinc-client directory, there is error message like can not open job.xml , can not parse job.xml.

Is there anyone knows where is wrong?
I would appreciate for your help.

First, forget about 'output files absent'. If the science application crashes, it produces no scientific output. That is inevitable, and not diagnostic.

Yes, stderr_txt is wiped from the client computer after the crash, but it can be found in two places:

a) Before the result is reported to the server, it can be found embedded in client_state.xml
b) After the result has been reported and acknowledged, it can be seen in the task record on the server

Thanks for your help, yes I have seen the stderr_text in the client_state.xml, the error message is'cannot acquire lockfile' , have any idea about that?

again,
thanks a lot for your help.
