Description:
------------
SOMETIMES, after POST-ing a form, a script hangs on any session-related function. This problm appears and stops at random. It only happens on one server, I haven't been able to reproduce it in any other environment

Reproduce code:
---------------
Eg. session_start() or session_register()

Expected result:
----------------
The session-related functions should work properly instead of hanging. 

Actual result:
--------------
Script hangs on first session-related function

I have exactly the same problem:

As jlampa described the problem appears and stops at random.

When I first load the page (no session started yet) I get the HTML code. After submitting the form nothing hapens and the page look lik it's stuck in a foreach/while loop.

When puttting exit; before session start (right before submitting) it doesn't happen.

So I am 100% sure that session_start() hangs for some reason...
 

submit.php:
===========

<?php
session_start();
?>
<form method="get" action="?">
    <select name="router" onchange="this.form.submit();">
        <option value="">select a router</option>
        <option value="Freebix" >br0.bru1.benesol.be</option>
    </select>
    <input type="submit" value="select"/>
</form>

=== END ===
