I haven't done much worked on this project in several years, so I can't offer much help other than the obvious Does that directory and file exist?. If the directory and file exist, there is some configuration issue. If the directory exists and the file is missing, I'm not sure what the issue is. I'd use a debugger to see why it is looking for that file.

@dain
The merged thread deletes the file. This operation is executed along with the read thread. The read thread does not know that the file has been deleted in a short time. Capture this exception and try to read it again. After 1- n times, it will go to the correct one File read data
