This got me to thinking....
Setup a POE::Wheel::Followtail for each? file you want to tail.? No need to spawn off other processes.
If you DO need separate processes, from the main process run a POE::Wheel::Run and start another kernel on that process.? Setup a Followtail wheel for the input and handle the output back to the Main code via STDOUT and the Run object.
I tend to use fork sparingly and if you need to do alot of things simultaneously, you should probably handle those in POE first.
HTH,
Dougie!!!

Subject: Re: POE and perl fork interaction
It's not clear what you're trying to do, but I suspect that you're doing
it wrong. :(?
?
Is there a reason why you don't use POE::Wheel::Run to tail the files??
?
There's also:?

?
I suspect that your forked tail process may have events queued from the
parent, as outlined in POE::Wheel::Run section on Nested POE Kernels.?
?
Good luck.?
