PostPosted: Mon Apr 10, 2006 3:19 am    Post subject: apache segfault w/ (only) cacti Reply with quote

my apache segfaults (just the individual process) when I visit my cacti site. this IS a new install, everything fully up to date as of 20060409 with ACCEPT_KEYWORDS="~x86". The db and the config file are setup properly.
I have two other cacti installs in the same config at work, w/ no issues. (their cacti installs were upgrades, not new installs as this one)

if more info is needed, please let me know.
thanks!

I'm seeing the same problem (the segfault is logged in error_log):

[Wed Apr 19 22:33:44 2006] [notice] child pid 8569 exit signal Segmentation fault (11)
[Wed Apr 19 22:33:53 2006] [notice] child pid 8671 exit signal Segmentation fault (11)
[Wed Apr 19 22:34:31 2006] [notice] child pid 8774 exit signal Segmentation fault (11)

I'll let you know if I get anything working. I'm sure I upgraded something and didn't pay attention to what I was doing. Maybe a revdep-rebuild will take care of it.

The thing that's bizarre to me is that it's not just php. I put a web-site in my user directory (/home/dave/public_html) with an index.php file that just had a call to <? phpinfo() ?> and that works fine. There's something in cacti I guess.

revdep-rebuild did nothing, nor did upgrading to ~86 php and rebuilding apache.

I found a post on the cacti forums here:
http://forums.cacti.net/about12805.html&highlight=apache+segfault but so far no one seems to have a solution.

Ok, I have no idea if this was the problem or not, but when I fixed it, cacti started working.

I noticed that my mysql wasn't working. I have a local phpBB installation that I use for testing stuff. It was broken. /var/log/mysql/mysqld.err had the following:

InnoDB: Error: log file ./ib_logfile0 is of different size 0 8388608 bytes
InnoDB: than specified in the .cnf file 0 5242880 bytes!
060420 23:27:29 [ERROR] Can't init databases
060420 23:27:29 [ERROR] Aborting

So I googled some stuff and it said that I could delete the ib_logfile0 and ib_logfile1.

I didn't delete them, but rather moved them elsewhere. I was then able to re-start mysql. Then my phpBB came up then I tried Cacti and it came up. Incredibly strange. Maybe this applies to you too?

Mine has been working great since fixing MySQL. Have you made sure your MySQL installation is good?

MySQL is working fine. Other Services and Scripts use it without problems.

Actually i simply posted to stay updated on this issue.
I dont have any working version at all :(

Could you please post me your working version or did you pull it entirely from portage?

I will probably drop php5 and get php4 once i have some more time.

Will let you know if it brings anything.

Cheers,

yep

ditched php5 and emerged the masked php4 and mod_php-4
cacti now works.

in package.mask :
Code:
 >=dev-lang/php-5

in package.unmask :
Code:
 >=dev-php/php-4
>=dev-php/mod_php-4


hope this works for you too.

:(
Don't install dev-php/php and/or dev-php/mod_php, they have exactly 12 days to live still, then they will definitively disappear from Portage.
If you want to use PHP4, just emerge =dev-lang/php-4* and you'll get the latest, security-fixed, PHP4 version! (dev-lang/php-4.4.2-r2)

do you have threaded version of apache 2?

If so try using nonthreaded, ie prefork, mybe it will work ;-) Some of my instalations would crash randomly when using worker module.

i am "unstable" :D (~x86 anyway)
dev-lang/php-5.1.4
net-www/apache-2.0.55-r2 (non threaded)
net-analyzer/cacti-0.8.6h_p20060108-r2

BUT, as i said, i have this EXACT configuration on 2 other boxes working fine. To me this has to be something on that machine...but what?

The same, but...
I've updated my box to php5 cacti dosen't work when in localhost/htdocs/cacti/ and the strangest is this that in localhost/htdocs/cacti_old my old 0.8.6h moved from old server works fine.

With this version cacti-0.8.6h_p20060108 (just copied from old box) there is no problem.
Code:

dev-lang/php-5.1.4  USE="apache2 berkdb cli crypt ftp gd hardenedphp imap ldap mysql ncurses nls pcre pic readline sasl session snmp sockets sqlite ssl threads truetype unicode xml zlib"

and

net-www/apache-2.0.55-r1  USE="apache2 ldap ssl threads"




Ok I've found where was problem in my box. I forgot to change in include/config.php
Code:

$database_type = "mysql";
$database_default = "cactidb";
$database_hostname = "localhost";
$database_username = "cactiuser";
$database_password = "cacti";
$database_port = "3306";

There is no problem right now.

Any clues? MySQL is fine, tried the account with other apps and they are working.
