removed local and every thing worked perfectly

No, it doesn't. The On function sets the signal handler globally, for ever, even after eval has finished. You want local $SIG{'ALRM'} inside that eval.

The extra subs don't make your code any clearer. I think you should keep alarm and local $SIG{'ALRM'} inside the eval.

You could also consider writing a generic timeout function like this:

# untested sub withTimeout { my ($timeout,$worker,$timeouthandler)=@_; eval { local $SIG{'ALRM'}=sub { die "TIMEOUT" }; alarm($timeout); $worker->(); alarm(0); }; if ($@ and $@=~/TIMEOUT/) { $errorhandler->(); } }
