I don't know how many connections you need to handle simultaneously, or how often connects/disconnects are made, but you might want to look at letting inetd handle the socket.
See RFC: A Simple Socket Server Using 'inetd' and A Simple Socket Server Using 'inetd' For a situation like "heartbeat monitors", it would seem prudent to keep each monitor connection a separate process, so if one goes haywire, it won't affect the others. If your parent thread goes down, for whatever reason, you will see all monitors fail. That will cause havoc for the nurses who are trying to determine which patient needs help.
I'm not really a human, but I play one on earth.

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).

or How to display code and escape characters
