Your warnings are from lines 41 and 43, your code only has 31 lines... what happened with the rest?

What is that syslog function your are calling in line 11?

I think, the following addresses your main cause for the warnings:

In line 25 you are working on the wrong variable. You should use $line for your regex match; not $_. Your line 25 reads as (ignoring the error at the end): ($participant) = $_ =~ m{(.....)/};

I would use lexical filehandles and would use more localized variables.

edit2: I have to correct me completely on that regex line; sorry:

Your line 25 does a regex match on $participant, which is not defined yet. So there is a regex match against an undefined variable. Line 26 wants to print that undefined variable as well.

The correction still is to do the regex match on $line and store the result in $participant

edit: fixed error and rephrased regex, sorry
