<![CDATA[Linux Forum — php[16463]: segfault at ffffffff ip 000000000058b19f sp 00007fffc76660]]> https://linuxforum.ru/viewtopic.php?id=36326 Wed, 15 Oct 2014 13:15:39 +0000 PunBB <![CDATA[Re: php[16463]: segfault at ffffffff ip 000000000058b19f sp 00007fffc76660]]> https://linuxforum.ru/viewtopic.php?pid=426651#p426651 дело в том что у меня стандартные скрипты, меняю только action:

/usr/share/nginx/html/Grab/index-console.php Test Action1
/usr/share/nginx/html/Grab/index-console.php Test Action2
/usr/share/nginx/html/Grab/index-console.php Test Action3

решил отключить глобально. посмотрим как будет работать.

спасибо большое за ответ.

На всякий случай можно отрубить GC только для проблемного скрипта, прописав в нем

ini_set('zend.enable_gc',0);

[root@linuxsrv2 ~]# gdb /usr/bin/php
.
.
(gdb) run /usr/share/nginx/html/Grab/index-console.php Test xxxxxxx
Starting program: /usr/bin/php /usr/share/nginx/html/Grab/index-console.php Test deyerlerorg
[Thread debugging using libthread_db enabled]
zend_mm_heap corrupted

Program exited with code 01.


выключения "garbace collector"-a решил эту проблему:

[PHP]
zend.enable_gc = 0


(gdb) run /usr/share/nginx/html/Grab/index-console.php Test xxxxxx
Starting program: /usr/bin/php /usr/share/nginx/html/Grab/index-console.php Test deyerlerorg
[Thread debugging using libthread_db enabled]

Program exited normally..

это хорошая идея выключить "garbace collector" навсегда?
