coredump solaris 8, php5.0.4, cacti 0.8.6c

[santm]

I am having core dump from this setup.

PHP 5.0.4
cacti 0.8.6.c
Apache 2.0.50
MySQL Client API 4.0.15


The core dump is not very regular but it is happening more often as I tried to add more and more machines for monitoring. The only way I can solve it is by rebooting the server.

Any help will be great.

The core dump was happening for the cronjob.

I am using pollar.php as it was mentioned in the upgrade doc. I was using cmd.php earlier with old version.

The problem looks like did not repeated in last 24 hrs after I modified my my.cnf for mysql. Now I am using example mysql config file for large systems that comes with mysql distrib.

I did this as I saw lot of mesgs. for mysql connections while doing strings to the core file.


Please let me know if you have any questions for me.

Well the problem did not got solved. It reappered again and after reboot it will go away for few days and start again. After that I am using the crontab entry from 'cactiuser' instead of root and it also has samr problem of doing the core dump.

Any help will be great. If you need the core file(1834812 bytes) let me know

Is your solaris 64bit?

Try building php without snmp support and use the net-snmp binaries instead. There was a bug JUST fixed to PHP where certain snmp information was being returned using the wrong size parameter, which can lead to segfaults.

If you use the latest patches to Cacti, the snmp.php patch will make it run pretty fast.

Alternatively, you can download the latest snmp.c from the PHP CVS if you are building from scratch and want to continue to utilize php_snmp module. You don't have to wait for PHP 5.0.5 to fix it.

I used this to build my PHP (5.0.4) last time. But I am not sure what you want to change. Can you please direct me here.

Code: Select all

'./configure' '--with-mysql=/files/Mysql' '--with-apxs2=/files/http2/bin/apxs' '
--with-gd' '--with-jpeg-dir=/usr/local' '--with-png-dir=/usr/local' '--with-zlib
-dir=/usr/local' '--with-snmp=/usr/local/net-snmp/'  '--enable-ucd-snmp-hack' '--with-libxml-dir=/usr/local/lib'

At the same time I am getting the snmp.c from php5 cvs as you mentioned if it is still needed.


And for the cacti patch(snmp.php) do I need rebuild cacti as well ?

-Thanks for help.

[TheWitness]

Yes, the distribution of 5.0.4 also contained the snmp.c bug. So download the file and place it in the source/ext/snmp folder prior to making.

To patch cacti, you simply need to get the files from http://www.cacti.net/downloads/patches/ ... re-patched and copy them over your existing ones.

You also have to recreate the include/config.php to the new format.

Well Php is installed with new snmp.c as you mentioned.
And I applied all the pre-patches from cacti web site for cacti.

Will update in a day or two if there is no more core dump other wise will update as soon as there is a core dump.

[santm]

Well the reappeared again any more help.
