One obvious problem with your code is that you open LINKS for appending, and then you try to read from it.

As far as I can see from a simple test, perl -e 'open(BLA,">>/tmp/bla"); while(<BLA>){print}'

The test shows that won't give you an error messages, but it will exit the loop immediately.

Which is why your webcrawler exits prematurely, without even reaching the calls to links. You should read from a different file than you are writing to.

(And you should step through it in debugger to see if what you think is happening is actualy happening.)

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
