GÜNCEL: PHP ldap_connect Apache Dişli () Çağrı

0 Cevap php

Ben komut satırında aşağıdaki PHP kodu çalıştırırsanız ben beklenen sonuç almak:

php -r 'var_dump(ldap_connect("ldaps://ldaps.example.com", 636));'
resource(4) of type (ldap link)

Ben bir PHP komut dosyası bu koymak ancak eğer

<?php ldap_connect("ldaps://ldaps.example.com", 636); ?>

Apache, bağlantıyı keser Örneğin bu ben komut satırından komut vurmak döner Curl budur:

curl http://example.com/ldap_test.php
curl: (52) Empty reply from server

Apache erisim.log bu sayfaya isabet gösterir ve asla hatalar.log boştur.

Ben LDAP sunucusu Ben diğer iki sunucularda bu test gibi çalışma olduğunu biliyorum. PHP 5.2.9 ve Apache çalışan bir Joyent hızlandırıcı üzerinde çalışıyorum. Apache bu boğulma neden herkes biliyor musun?

Update:

Bugün sorun, komut dosyası çalışırken GDB kullanarak Apache ayıklanmış. Komut ldap_connect () satırı çarptığında ben GDB şu olsun:

Program received signal SIGSEGV, Segmentation fault.
0xfe94b8bb in _free_unlocked () from /lib/libc.so.1

Ben henüz segfault neden olduğunu emin değilim, ama en azından ben Apache aslında çökmesini olduğunu biliyoruz.

İşte tam backtrace olduğunu:

Breakpoint 1, 0x08094417 in ap_process_request ()
(gdb) c
Continuing.

Update 2:

Ben sorun bu iki işlev çağrıları başlar ne söyleyebilirim:

#3  0xfde3f78b in ldap_free_urldesc () from /usr/lib/libldap.so.5
#4  0xfd0943d9 in ldap_free_urllist () from /opt/local/lib/libldap-2.4.so.2

# 4 (ldap_free_urllist) in fonksiyonu / opt/local/lib/libldap-2.4.so.2 bir kütüphane denir ve # 3 / usr/lib/libldap.so.5 bir kütüphane denir. Bunun normal olup olmadığını söylemek için yeterince bilmiyorum, ama ben değil varsayılabilir. Yani bir şekilde bu LDAP kütüphanelerin hem yüklü alıyorsanız.
