Description:
------------
Hi,

Every night I do a log rotation and I use the command ./bin/apachectl
graceful
Apache was down and I see the same error in logs :


It seems that the problem comes from PHP version
(http://bugs.php.net/bug.php?id=27735).

However on this server I use the oracle instant client oci8, Solaris 9,
Apache 2.0.52, PHP 4.4.1 

I've test compilation on PHP-4.4.1 --without-pcre options and i've same problem.
I've downgrade PHP version to 4.3.4 : same results.
I've downgrade Apache to 2.0.48 : and no is it ok.

I've also post a mail to users mailing list Apache.

Do you have a patch for my PHP-4.4.1 ? 

Actual result:
--------------
[Thu Nov 03 03:10:01 2005] [notice] SIGUSR1 received.  Doing graceful restart
[Thu Nov 03 03:10:02 2005] [notice] seg fault or similar nasty error detected in the parent process

What MPM are you using with Apache2?
 [2005-11-08 11:37 UTC] david dot micheneau at in-fusio dot com 
I use MPM worker.
for information see my compilation conf :
"./configure" \
"--prefix=/opt/local/http-2.0.55" \
"--with-mpm=worker" \
"--disable-ssl" \
"--disable-auth-dbm" \
"--with-perl" \
"--disable-cgid" \
"--enable-cgi" \
"--disable-suexec" \
"--enable-vhost-alias" \
"--disable-ssl" \
"--enable-alias" \
"--enable-proxy" \
"--enable-headers" \
"--enable-sigchild" \
"--enable-rewrite" \
"--enable-so" \

Threaded Apache2 is not really supported by PHP.
Can your reproduce this when using the prefork MPM?
 [2005-11-08 14:30 UTC] david dot micheneau at in-fusio dot com 
Yes same problem with prefork MPM.
See the back trace: 

(gdb) bt

Did you reconfigure/compile PHP?
 [2005-11-08 15:23 UTC] david dot micheneau at in-fusio dot com 
oups...sorry i forget to recompile PHP.

So a new comportment with prefork option.

[Tue Nov 08 15:20:25 2005] [error] (12)Not enough space: fork: Unable to fork new process

But we have enought space on the server:

root@longnose: /home/hot/php-4.4.1 >df -h
Syst?me de fichiers  taille utilis?  dispo capacit?  Mont? sur
/dev/md/dsk/d0         4,8G   4,2G   556M    89%    /
/proc                    0K     0K     0K     0%    /proc
mnttab                   0K     0K     0K     0%    /etc/mnttab
fd                       0K     0K     0K     0%    /dev/fd
swap                    16M    40K    16M     1%    /var/run
swap                   158M   142M    16M    90%    /tmp
/dev/md/dsk/d7          26G   5,8G    20G    23%    /data

And now it's impossible to stop Apache correctly...i've 29 httpd process before the error message in logs.
 [2005-11-08 17:04 UTC] sniper@php.net 
So, what makes you think this is a PHP problem?
 [2005-11-09 08:59 UTC] david dot micheneau at in-fusio dot com 
i'll try to compile with Apache-1.3...i've read an article about oracle instant client, and Apache foundation recommand to use Apache 1.3 with oci8 driver: http://www.oracle.com/technology/pub/notes/technote_php_instant.html
 [2005-11-09 09:51 UTC] david dot micheneau at in-fusio dot com 
So now is it working well with Apache-1.3.34, PHP-4.4.1 and oci8.
I think really that the problem don't come from PHP.

Thanks.
