As others have posted, if the process is well-behaved, you should be able to rename the file then send it a SIGHUP and it should start using a new file. You might have to create the new log file using something like "touch" first, though.

If that doesn't work, the application is broken. Assuming you have an uptime requirement, the failure of the application to properly handle log files is causing it to fail to meet its uptime requirement. Make the developer fix it.

Because it's broke.

Just because the developer didn't THINK about the impact of of failing to manage log files doesn't mean it's OK to fail like that.

paranoid::log::file

Paranoid::Log::File(3pm)				User Contributed Perl Documentation				  Paranoid::Log::File(3pm)

NAME

       Paranoid::Log::File - File Logging Functions

VERSION

       $Id: File.pm,v 0.83 2010/04/15 23:23:28 acorliss Exp $

SYNOPSIS

	 use Paranoid::Log;

	 enableFacility('events', 'file', 'debug', '+', $filename);

DESCRIPTION

       This module logs messages to the log files, and is safe for use with forked children logging to the same files.	Each child will open their
       own filehandles and use advisory locking for writes.

       This module should not be used directly, Paranoid::Log should be your exclusive interface for logging.

SUBROUTINES
/METHODS
       NOTE:  Given that this module is not intended to be used directly nothing is exported.

   init
   log
   remove
   dump
DEPENDENCIES

       o   Fcntl

       o   Paranoid::Debug

       o   Paranoid::Filesystem

       o   Paranoid::Input

SEE ALSO

       o   Paranoid::Log

BUGS AND LIMITATIONS

       This isn't a high performance module when dealing with a high logging rate with high concurrency.  This is due to the advisory locking
       requirement and the seeks to the end of the file with every message.  This facility is intended as a kind of lowest-common demoninator for
       programs that need some kind of logging capability.
