in reply to Need Help in threading perl

Does the problem happen without threads?

You did not output $branchfile in your error message. Output $branchfile in your error message and inspect if the file already exists at the location and if the current user can create files there.

      You are using chdir from within a thread. I would avoid that, since it is never clear between operating systems, whether the "current directory" is per-thread or global per program.

      Also, replace

      system "mkdir $branchdir";

      with mkdir:

      mkdir $branchdir;

      Also, output the filename and path in your error message. I already suggested that to you but you ignore it. Please explain why you ignore my advice.
