This is nothing abnormal - you are checking the wrong variable.
You should really check $? before looking at $!.
Please, open your perldocs to
perlvar and read
$! If used in a numeric context, yields the current
value of errno, with all the usual caveats. (This
means that you shouldn't depend on the value of $!
to be anything in particular unless you've gotten a
specific error return indicating a system error.)
Note the parenthetical part. There is also a long section
in
perlvar ( under the title Error Indicators )
that may help you out a little.

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).
