If a read is in progress when the 10 seconds times out, then the heartbeat will be delayed until the read completes.
Sure, and if that's a problem, send it after 9.8 seconds, or some other interval. Read in small chuncks if that's required. Or just use a separate process.
But can two concurrent processes talk from the same local port concurrently?
Whether or not that's possible is irrelevant (however, this is UDP we're talking about, it's isn't about armies of ogres having to exit a tower through a narrow gate), as that is not what the OP seems to be doing. To quote him:
The client sends the first heartbeat from ports: 53036, 53037, 53038, 53039 to ports 8020, 8019, 8008, 8003. This repeats in every 10 seconds.
Oh, and do note that in my sketch, there's just one program anyway.

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).
