apache 2.0.63 crash on restart ... php related (very old problem)

[edhunter]

Hello

I know this has been discussed on lists and other forums, but so far I cant get rid of this issue.
The problem is that apache crashes (but no every time) I run apachectl restart. I understand that this is related to php and may be to the order of extensions in extensions.ini. Yesterday I updated php and extensions from 5.2.6 to 5.2.8. I hoped that this could be fixed :). But now I still have this issue. I have used a script to fix order of extensions (here it is: http://www.pingle.org/2007/09/22/php-crashes-extensions-workaround ), but it didnt help me too.

Here are some details:

10x in advance

Hmm, what's the output when you use apachectl? Try and upload the httpd.core and I'll have a little look.

[edhunter]

there is no output on console
#:> apachectl restart
#:>

from messages:

from httpd-error log:

might be php related i think...

if you type php -v do you get a segfault?

for me it was the recode.so extension in extensions.ini that i had to put up top

try moving session to the top...changing the order of php extensions loading perhaps?

I've had crashing problems with mhash extension, try commenting that one out.

i commented it ... (i'm not sure if it is really needed for my webs) but i still got crash on apachectl restart.

i dont get segfault on php -v
i dont have recode extension...
there are too many combinations for order of extensions, in my first post i said that i have used a tool for it, that didnt help me too.

[liamjfoy]

After a quick google there just seems to be many people with this issue and little resolve. I believe there is also a FreeBSD PR.

[r-c-e]

What does the apache error log say? What about apachectl configtest?

[edhunter]

@r-c-e
error log says
[Wed Dec 10 17:17:32 2008] [notice] SIGHUP received. Attempting to restart
[Wed Dec 10 17:17:32 2008] [notice] seg fault or similar nasty error detected in the parent process

apachectl configtest says Syntax OK

[p3n1x]

my next suggestion....this is strange

maybe move onto apache 2.2.9, is there any reason you cannot move?

[p3n1x]

reading over this again have you tried not loading any php extensions at all? perhaps making sure it is php related.

also that pingle.org link you had in ive used that in the past too. works great. but in the end i just stick recode and session up top.

but we are using different versions of apache as im in on 2.2.9

[edhunter]

@p3n1x
A few months ago I used apache 2.2 and php 5.2.6 and I had same problems, then i deinstalled 2.2 and installed 2.0 as suggested by friend. I think that this issue is not related to apache version (2.0 and 2.2 - it was same behaviour for me).
I commented all extensions - and there is no crash on apache restart, but the primary web site does not fuction properly. It is completly sure that the problem is php related.
I dont have recode. I have tried moving session on top, but it didnt help :) There are realy too many combinations for the order of extensiosns.

[p3n1x]

heres my extensions.ini file if it helps?

[edhunter]

thank you

I dont have so much extensions, but I followed the order of yours. And I did apachectl restart ... and on the 3rd restart i got BANG :(((
You say that this is the order of extensions and that you are using apache 2.2.x and you dont have troubles on restart.

What version of freebsd ?

Hmm I'll move to latest apache 2.2 again and will try it again.

[p3n1x]

freebsd 6.4 release

apache 2.2.11 (just updated ports)
php 5.28 or whatever it was. and yea.

[Draug]

I have this problem too...
Comment extension=spl.so in php.ini, it work, but not solved problem.

[cyberguss]

I had the same problem, looks like it is related to php extensions,
mhash is definitely one of them.

I also had to move mysql.so to the first line and session.so to the second.
After restart Apache is no longer crashing.

Below is my /usr/local/etc/php/extensions.ini
extension=mysql.so
extension=session.so
extension=ctype.so
extension=pcre.so
extension=simplexml.so
extension=spl.so
extension=dom.so
extension=fileinfo.so
extension=filter.so
extension=gd.so
extension=gettext.so
extension=hash.so
extension=iconv.so
extension=json.so
extension=mcrypt.so
#extension=mhash.so
extension=pdo.so
extension=pdo_sqlite.so
extension=posix.so
extension=sqlite.so
extension=tokenizer.so
extension=xml.so
extension=xmlreader.so
extension=xmlwriter.so

Actually the problem thisappeared - I moved to latest apache 2.2 from ports apache-2.2.11_3
No more crash ot apachectl restart :))))))
