n Cron.pm we have this line in function execute .
$log->(0,"Schedule::Cron - Starting job $index $args_label")
In my case the error log if file printed like this
=================LOG====================================
Schedule::Cron - Starting job 0 with (HASH(0x83a9464))
Schedule::Cron - Forking child PID 22934
Executing generate_infobundle 07/02/02 02:00:00
=================LOG====================================
Is it possible to Dump the Hash(may be using Data::Dumper) so that we
get a human readable information
