unlink file succeed and no content for the file but the file is still there
I used Perl to detect a directory. If there is a new file coming, I copy this file to dest directory and then unlink this file from the src directory. Most cases are good. But in some rare cases, the file is still left in the src directory. Actually the left files had been copied to dest directory successfully. The left files are zero in size. This rare case usually happens in integral point clock. Does anyone has this problem before?
