Question

Apache Log File: Parent: child process exited with status 4294967295/3221225477 -- Restarting.

Asked by: virmaior

[Tue Dec 07 13:15:29 2004] [notice] Parent: child process exited with status 4294967295 -- Restarting.
[Tue Dec 07 13:15:29 2004] [notice] Parent: Created child process 5340
[Tue Dec 07 13:15:29 2004] [notice] Disabled use of AcceptEx() WinSock2 API

[Tue Dec 07 13:15:30 2004] [notice] Child 5340: Listening on port 80.

I keep getting server crashes, and I can't identify the cause.
This will be in the log around a crash.

child process number varies (randomly)
error is either4294967295 OR 3221225477 (mostly the former)

closest I can get to a diagnosis is a couple listed (but not really solved php bugs):
http://bugs.php.net/bug.php?id=26286
http://bugs.php.net/bug.php?id=25570

PHP 5.0.2 + Apache 2.0.50 + Windows XP
(goes away on 5.0.3RC1 but I'm seeing another more pernicious problem with that for right now)

I can't identify it down to a single script error.  I stripped out/reduced the use of ob_start, have started simplifying and recoding segments to see if this decreases frequency.

Any guesses?

To my knowledge and according to http://natune.net/Artikel/Anleitungen/PHP/230, the bug is caused by a request of a php script, which contains POST-data.

If you use eg. opera (may be mozilla too) the transmition will be canceled or an other error happens. If you use InternetExplorer, apache craches due to incorrectly memory access.

The error is confirmed with the following versions: Apache 2.0.46 and 2.0.47 with PHP 4.3.0 - 4.3.3 on it.
Other versions might been affected, too.
To solve the problem, you could try an earlier Apache version (before 2.0.46, better 1.37). Or try using php as a module instead of CGI or the other way.

Try to comment out the script line per line to to find out which exact line in your script causes the crach.

My german isn't great.  That's somewhat helpful..  I'm not quite sure what to make of it however.  Is it something in my pages that is propogating malformed POST data or is it just Internet Explorer demonstrating its W3C compatibility again?  (making changes to my code seems to impact the frequency of the errors).

 

by: caterham_wwwPosted on 2004-12-20 at 08:24:56ID: 12867855

I've basically mentioned what the article says.
So far as I understood, there is POST Data submitted eg. someone fills out a form and then this data should be handled by a php script. But in someway the whole thing crashes. Other browsers abord loading the page, too. So this is not a W3C compatibility problem. It's a problem of the interaction between Apache and PHP with POST-Data in the request-(headers).

May be you can find one single line in the php script causing the crash. According to the article, sometimes it could be just one line in the code.

the 3221225477 error is explained at http://bugs.php.net/bug.php?id=31300&edit=1
it has to do with string concatenation within a an array access operator
e.g. $myarray['ab' . '_cd'] will crash for some reason even though $myarray['ab_cd'] works

the 4294967295 fixes in PHP 5.03. (or the latest version of 4.1)

I found this link which so far has solved this issue for me:  http://www.java-samples.com/showtutorial.php?tutorialid=1050

This is what the link has to say:
If you are getting this error, you are probably trying to use Apache, MySQL and PHP in a windows system. Just do this simple step to solve this issue.

It is quite frustrating to see that all your PHP pages suddenly doesn't seem to work. If you check your Apache log file you will see this error: Parent: child process exited with status 3221225477 -- Restarting

Don't worry just goto the PHP installation folder and look for libmysql.dll file.

Just copy this file and save it to your windows\system32 folder.

Now restart MySQL and Apache servers.

Everything should be fine now and all your PHP pages will work as normal.
