Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

we have problem with many JOOMLA sites on our servers.

Error is only Segm. fault 11. In browser is "no data". After debug trace I have this.

¨Core was generated by `/usr/sbin/httpd'.
Program terminated with signal 11, Segmentation fault.
#0  0x00007f6985296721 in tsrm_realpath_r (path=0x7ffff2bab270 "/www/domain.cz/domain.cz/language/cs-CZ/cs-CZ.xml", start=1, len=53, ll=0x7ffff2bab26c, t=0x7ffff2bab260,
    use_realpath=1, is_dir=1, link_is_dir=0x0) at /usr/src/debug/php-5.3.3/TSRM/tsrm_virtual_cwd.c:609
609     {

UPDATE 1

(gdb)  print (char *)executor_globals.active_op_array->function_name
$2 = 0x7f699711e3d0 "getMetadata"
(gdb) print (char *)executor_globals.active_op_array->filename
$3 = 0x7f6997088da8 "/www/domain.cz/domain.cz/libraries/joomla/language/language.php"

Can you help me please, where can be problem?

Is debug mode enabled in Joomla? –  Nathan C Jan 23 at 14:21
    
Yes, but without effect. Browser show "no data response". Error log with E_ALL contain Segm. fault only. –  Pavel Jan 24 at 12:01

Ok, I have it!

So, problem is with Piwik. As is described here:

http://dev.piwik.org/trac/ticket/4409#ticket

In one version was used libxml_disable_entity_loader() - this fce. is not thread safe. So this do faults of JOOMLA sites.
