( #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
