Apache crashes during install

Hi,
I want to try the MODx Revolution but I am not able to install it - during every attempt to install it, Apache crashes after I click Install button.
I tried alpha 6, then I tried the most actual revisoin from SVN but still the same thing. I followed this manual: http://svn.modxcms.com/docs/display/revolution/Development+and+Testing+Notes
Apache logs says:
[Sun Jan 18 22:18:28 2009] [notice] Parent: child process exited with status 255 -- Restarting.

I found some topics about this, but none of them solved this.
I am running XAMPP 1.7.0 with
Apache HTTPD 2.2.11 + Openssl 0.9.8i
MySQL 5.1.30
PHP 5.2.8
on Windows Vista Home Premium.
MODx 0.9.6.3 is running OK

So what am I doing wrong?

I don’t know what’s causing it, but it does exactly the same thing for me if that’s any consolation.

I don’t think you’re doing anything wrong.

Have look at this ticket I’ve raised, http://svn.modxcms.com/jira/browse/MODX-604 and MODx-596 for that matter, it may shed some light. I’ll do some more investigation here into this.

I’m sorry, but this is almost definitely going to be issues with the MySQL drivers compiled into PHP for MySQL 5.1.x. Both MySQL 5.1 and PHP 5.2.8 are barely a month old, so there are likely going to be issues, especially considering this is the first GA release of MySQL 5.1. I suggest sticking with a stable environment.

OK, but I have 3 environments here, Centos5(very stable), Fedora 7(not so stable) and Win2Kwith XAMPP(old but stable) and this has affected all of them at one time or another, also I can re-create the fault at will. I think at the mo it will only happen during installation and then only if the install causes a log message to be output hence its a bit elusive,

I use:

Apache/2.0.59 (Unix) PHP/5.2.6 DAV/2 on Mac OSX Leopard
MySQL 5.0.41

...and have had no occurrences of that error.

I run a CentOS box using Apache 2.2.9 + PHP 5.2.6 + MySQL client API 5.0.45 + MySQL server 5.0.45, a Macbook running OS X with Apache 2.0.59 + PHP 5.2.5 + MySQL client API 5.0.41 + MySQL server 5.0.41, and every version of XAMPP released for Windows (XP Pro here) in the past 5 years. I’ve seen none of these errors on any of these environments except specific recent versions of XAMPP (especially the ones with MySQL 5.0.51 or PHP 5.1.6, and now the most recent ones with PHP 5.2.8 and/or MySQL 5.1.x).  The only environments I’ve ever actually encountered problems like this in are where MySQL client API and server versions differed in the compile, along with these most recent combinations of Apache+MySQL+PHP.

Hmm, I’m starting to wonder now, how many of your platforms have xdebug on them? It’s this that’s picking this up on mine. I’m not sure where this ’100 nested calls’ limit comes from, who sets it, why its this value etc. I’ll look at this. I have several Centos5 platforms, some are clean, i.e don’t have xdebug or a dev environment as such, I’m not sure I’ve seen this everywhere when I think more about it.

>>>Ok, found the limit, its an xdebug setting, even if I change this to 1000 I still get recursuin around these lines :-
15 0.2713 5069632 xPDO->log( ) ../xpdocachemanager.class.php:153
16 0.2713 5069680 modX->_log( ) ../xpdo.class.php:1384
17 0.2713 5069896 xPDO->_log( ) ../modx.class.php:2539
18 0.2714 5071440 xPDOCacheManager->writeFile( ) ../xpdo.class.php:1438

BTW my centos5 box gives me the following :-
httpd-2.2.3-11.el5_2.centos.4
php-5.1.6-20.el5_2.1
mysql-5.0.45-7.el5
mysql-server-5.0.45-7.el5

As far as I know this is stock, i.e a fully updated box.

OK, think I’ve found the cause, please look at last comment here

http://svn.modxcms.com/jira/browse/MODX-604

but, why does it sometimes fail on Windows?

I tried older version of XAMPP (1.6.8) with:
Apache 2.2.9
MySQL 5.0.67
PHP 5.2.6
And everything was installed OK - so I guess somebody should post a PHP bug report..
