Event though if the criteria is not matched i am sending a dummy text to the file" as below atleast this message should write into that file.
Hm. That covers teh situation where there are no new messages. What about where there are new messages, but none of them match your regexes?
At the time of error when i open the app_output file it remains blank.
An existing but empty file would not "fail to open" at line 444.
But then your error message does not reflect the situation you are actually testing.
If the file is empty, the open (inside File::Slurp::read_file() would succeed, but then the function would return no lines. Your code would detect the absence of any input and report it as an open failure.
But you are still not supplying the full error message ($!)
You better next time else I'm giving up on you.
