As dave_the_m pointed out, there are situations in which taint checks are automatically turned on.

If you really must run without taint checks you can use the -U switch in the shebang line. However, these checks are a good help in most cases and a daemon like yours should probably turn them on explicitly.

The error message you are getting reports a probably insecure use of tainted data, i.e. data passed from the outside into your program that has not been checked to be valid. Neglecting such checks may enable users to trick your program into performing actions you did not intend. This is especially dangerous in programs running with other privileges than the user who called them, which is why taint checks are turned on by default in setuid situations. See perlsec.

Update: Technically, the -U switch does not actually turn taint checks off. Rather, it allows unsafe operations. You will still get taint warnings if you have turned on warnings.
