Re: Task Failure -- Need Answer for this..............!!
It looks to me like the qvw file is write locked by some (possibly stopped, failed or dead) process. Can you rename the file? If you can, then the file is not locked.
Check the document log (if enabled - MyApplication.qvw.log) as it usually contains more information on why the reload failed.
Check for a qv.exe process that should not be running. You can kill this process if it is locking the file. Failing these, you may need to look at any qvb.exe processes and the server processes, but you obviously need to be more careful about killing any of these.
