( #3333=superdoc: print w/replies, xml ) Need Help??

First of all, File::Tail is on CPAN - there is no need to post it all here.

Having said that, I think you are running into some kind of a timing problem. File::Tail tries to be clever about detecting when a file has been rotated, and it seems that, under very heavy loads, it sometimes gets a false positive (it thinks that the file has been rotated when it really has not).

I've never been able to generate a reliable test case that would trigger that bug so I could debug it.

My advice is:

  • See if bumping maxinterval to a higher value helps
  • See if bumping adjustfter to a higher value helps
  • (may not be feasible for your application) put 0 or a small positive value into reset_tail - that will make it restart from the end of the file, or n lines from the end of the file - which might be better for your application that starting from the very beginning.

Hope this helps

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
