Reported By: robert at profundis dot se
Status: Open
Bug Type: Apache2 related
Operating System: Windows XP Professional SP1
PHP Version: 4.3.3
New Comment:
After some investigation it seems as this bug was introduced in PHP
4.3.3RC3. I have tested the following versions:
4.3.2 -- OK
4.3.3RC1 -- ?
4.3.3RC2 -- OK
4.3.3RC3 -- Crash
4.3.3RC4 -- Crash
4.3.3 -- Crash
4.3.4-dev -- Crash
With the versions designated 'OK', I was unable to reproduce the bug.
The '?', I didn't test.
I performed the test by constantly reloading (holding down F5) on a
<?php phpinfo(); ?> document.

<?php
// OS: Win 2000 Professional

// It worked on older versions of PHP/Apache,
// on PHP 4.3.3/Apache 2.0.47 it causes a browser
// crash
$todisplay = "";
for($i = 0; $i < 300000; $i++) {
$todisplay .= "Hello word<br>\n";

Description:
------------
Platform:
Apache 2.0.47 / PHP 4.3.3
Windows XP Pro SP 1
Problem:
It is similar to bug 24958 (http://bugs.php.net/bug.php?id=24958),
reportedly fixed a while ago, but...
In short: Sometimes a request cause Apache/PHP to crash, and restart
itself.
This first came to my attention when a visitor complained that very
often two pages failed to load (the notorious IE "error" message). I
noticed that these two pages where the largest PHP generated ones, 12 &
14k while others were about 5-6k. A sniff revealed that the TCP session
was terminated immediately after the request to these pages.
I then noticed in Apache's error log a frequent line:
"[notice] Parent: child process exited with status 4294967295 --
Restarting"
I now understood that this happens from time to time to others as well,
but that the request was resubmitted so it simply produced a little
delay while Apache was restarting. However, I cause Apache to crash
perhaps 1 time in 20 requests to this page, while this visitor seem to
do it 3 times in 4 requests. No clue what would make this difference.
I am now usually able to reproduce this myself, by quickly reloading
the page; the bigger the output, the more likely it is to cause the
crash.
A document like this:
<?php for($i; $i < 15000; ++$i) echo '-'; ?>
And requesting it two times in perhaps 2/10 second, will in almost all
cases cause the crash.
I have also verified this behaviour in the latest stable 4.3.4-dev
build (php4-win32-STABLE-200309170430.zip).
I cannot trace this crashing (in the log) before a few days ago when I
upgraded from 4.3.1-dev to 4.3.3.
Regards,
Robert Andersson
