mvandenb has asked for the wisdom of the Perl Monks concerning the following question:

Esteemed monks,

I searched CPAN, but could not find what I need.
I'm looking for a module to which I could pass a sub ref and a number. That module would then fork that number of processes, which would execute the passed sub ref.
I need that module to restart a process with the same sub, should it die.

Ideally, this module would also allow me to modify the number of processes at runtime, a bit like Log::Log4perl's behavior can be changed on the fly by changing a configuration file.

Does anyone know if such a module exists ?

Thanks in advance for your wise advice.

    A quick scan of CPAN reveals Parallel::ForkManager. This should go some ways towards your goal. You can implement the watchdog behaviour using the callbacks featured in that module, but a cursory glance at the docs does not reveal a way to modify the number of children during runtime, so I'm afraid this module might not help you there

    Don't know if can be what you need, but you can have a look at POE.

    Howdy!

    Net::Server may also suffice, if you run in the pre-forking mode.
