Apache crashes at graceful restart

[Bart]

Hi,

When apache receives a graceful restart it crashes with the following error:

[Thu May 18 23:18:16 2006] [notice] Graceful restart requested, doing restart
httpd in free(): error: chunk is already free
[Thu May 18 23:18:16 2006] [notice] seg fault or similar nasty error detected in the parent process

I'm running Plesk 8 (without the last patch) on FreeBSD 6.0.

My httpd.conf is straight forward, using prefork MPM. I've also installed Zend Optimizer 3.

Thanks for any input,
Bart

I tried the latest patch for Plesk, but it didn't resolve the problem.

I could trace the problem back to PHP. When I commented the LoadModule php4_module, the problem disappeared. This of course disables PHP and I don't want that, so I uncommented the line again..

After that I went to check out the php.ini file, I commented the Zend extensions and now the error disappeared. The problem must be with Zend Optimizer then..

I upgraded Zend Optimizer 3.0.0Beta3 to Zend Optimizer 3.0.0, but the problem persisted.

I got it working though with these parameters in the php.ini file:

[Zend]
;zend_extension_manager.optimizer=/usr/local/psa/Zend/lib/Optimizer-3.0.0
;zend_extension_manager.optimizer_ts=/usr/local/psa/Zend/lib/Optimizer_TS-3.0.0
zend_optimizer.optimization_level=15
zend_optimizer.version=3.0.0
zend_extension=/usr/local/psa/Zend/lib/ZendExtensionManager.so
;zend_extension_ts=/usr/local/psa/Zend/lib/ZendExtensionManager_TS.so

The standard Zend Optimizer php.ini didn't work. I hope somebody finds this useful.

I'm having a similar problem with php5 and no Zend. any ideas?

Something interesting i found.

apparently the order in which you load php extensions makes a difference.

some people suggest putting these in the following order at the very bottom of

/usr/local/etc/php/extensions.ini

....
extension=recode.so
extension=mysql.so
extension=imap.so
extension=sockets.so

(you may not have all of these loading, so only reorder the ones you already have)

my previous post actually did not help, so don't bother with it.
