Hi,

If you don't need a new fork, with the POE::Wheel::Run, you can try this ..

Create a new inline_states in the POE::Session->create

clean_db => \&clean_db_h,
[download]

and in the method, call the delay method like this

sub clean_db_h {

  # do all the clean needed in the db

  #
  # next clean in 3600 sec
  $_[KERNEL]->delay( clean_db => 3600);
};
[download]

With this, your clean_db method will be called every hour.
