I am having a problem with the File::Tail module.

I have a production script that uses File::Tail and it is missing lines of the logfile. The code looks similar to below.

I have duplicated the issue on a non production machine. Below is the strace –p output and code… File::Tail is not processing all 6000 lines I am writing to the log file (that file::tail is tailing). I have tried many different settings for File::Tail, with no resolution. I do see that the shorter each line that I log, the more lines show up in file.tail’s output. That lead me to thinking it was a buffer issue, but playing with the maxbuf setting didn't help. I also tried changing tail, reset_tail, as well as maxintercal, and interval. Additionally, the debug=>10 or debug=>1 doesnt seem to have any effect.

Non-prod code:

my $file=File::Tail->new(name=>"/tmp/fakelogfile",maxbuf=>"1024",debug
+=>10);
open (OUT,">/tmp/fakeoutputfile") || fatal_error("Coudn't open output 
+file");
while (defined(my $line=$file->read)) {
print OUT "I got: $line";
}

Code I use to generate the log file:

for (my $line_num = 1; $line_num <=6000; $line_num++) {
  open LOG,">>/tmp/fakelogfile";
  print LOG "$line_num\n";
  close LOG;
}
