What versions of PHP5, cacti, snmpd, etc have you installed? Is there any specific php scripts which causes this segfault?

[Villet (likeville)]

Hi i checked versions cacti it´s 0.8.7b and "snmp" it´s net-snmp-version 5.4.1. There it´s some scripts what i run and their folder are /usr/share/cacti/site/scripts. But cacti it´s but i didn´t find erro messages "cacti" logs. And both installations i did binary packages like apt-get install. But i didn´t get why php show error messages after i type dmesg. And this messages "1360781.168791] php5[29990]: segfault at bf3a1cf8 ip b7e19d5c sp bf3a1bc0 error 6 in libpcre.so.3.12.1[b7e08000+30000]" i can´t find libpcre.so anywhere where i can configuring that. Scripts what i running i cheked scripts running fine manually, but i can check agen.

And by the way my PHP version it´s PHP 5.2.6 and Zend Engine v.2.2

Can you please be more specific regarding your version? Different release of Ubuntu may contain packages based on the same upstream version, but with different patches applied. A command giving good information is "apt-cache policy packagename"

I experienced the same problem and found the cause in my case. My system is based on Jaunty and updated every day.
In my case the error message appeared every minute in my /var/log/messages file. Therefore I traced through the cron.d. It appeared that the serverstats process was the only one starting every minute.
After commenting this out the error message disappeared.
If I have some spare time I will run through the code of /usr/share/serverstats/update.php where the segfault is caused.

This bug is already reported in the Debian and Ubuntu launchpad:
