PHP和OCI8在连接时产生HTTPd Segmentation Fault(不是每次)

Question

我正试图调试PHP + OCI8的一个奇怪的问题，连接到Oracle (12c标准和19c企业)，这是发生在一个特定的服务器/实例，但我的测试/开发实例，或其他任何地方我看到它发生…

症状:

• 似乎在Apache HTTPd进程中随机生成一个分段错误。- HTTPd error_log或php_errors或xdebug中不会产生任何内容。只是没有信息

  [core:notice] [pid 7613:tid 1] AH00052: child pid 11863 exit signal分割错误(11)

• 可以连续工作1- x次，然后产生错误，或者不工作20次，然后有一个随机的喷射，它工作1、2或5次而不产生段故障。

• 同样一段简单的代码在许多其他实例上都能正常工作，甚至不会出现问题或产生任何异常。

• 当它失败时，大约15-20秒没有任何事情发生，然后脚本失败，HTTPd进程产生分割错误，然后浏览器/php/HTTPd重试几次，它可能会或可能不会在后续尝试中工作。

简单测试代码:

<?php
echo "test oci</br>";
$dbstr = "(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521 )) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = svc) ))";
$conn = oci_pconnect('user', 'pw', $dbstr) or die (ocierror());
if ($conn) { echo "Connected to Oracle</br>";  }
if ($conn) { oci_close($conn); }
?>

我们已经尝试过/看过的:

• 查看5个HTTPd进程的内存使用情况，没有一个接近php.ini中当前256M的设置。

• 安装/安装OCI8 2.2.0手动(下载/配置/制作/构建)和使用PECL。(卸载后重新运行，以防出错)

• 得到了一个核心转储，它显示了一些OCI8的东西在那里，但我失去了我正在寻找的东西。

• 测试了相同的代码Win10/Oracle 12c/19c/PHP7.4/HTTPd 2.4, Centos7+Oracle 19c, Centos7/Oracle 12c标准，Centos/Windows客户端/PHP/HTTPd对Solaris 19c企业，所有的行为都如预期的。

• 测试SEGFAULT发生时的模式，例如在X次之后等，但出现随机

环境:

这是在PHP 7.4, Apache 2.4, Solaris 11 (SPARC)， Oracle InstantClient 19, OCI8-2.2.0。

有没有人知道你会尝试什么或者如何去确定这个原因?

我在文档中注意到了这个有趣的注释https://www.php.net/manual/en/oci8.requirements.php

Oracle Instant Client provides its own LDAP library that may be incompatible to the LDAP library provided by the operating system.
Segmentation faults and other errors can happen if you load an OCI8 extension into a PHP containing LDAP support or if you load a PHP module with OCI8 into an Apache server with LDAP support.
But this depends heavily on the exact versions of operating system, system LDAP library, PHP,  OCI8, and other pieces of software involved.

但是，我没有看到Apache HTTPd正在加载任何ldap模块…

还有一个有趣的转折，在这个特定的实例上，有一种方法可以工作(不会产生分段错误)，那就是当连接对象和oci_pconnect在包含的文件中执行时-参见脚本的第二个版本…

initialize.php

<?php
$dbstr = "(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521 )) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = svc) ))";
$conn = oci_pconnect('user', 'pw', $dbstr) or die (ocierror());
?>    

testoci.php

<?php
require_once('initialize.php');
echo "test oci</br>";

if ($conn) { 
echo "Connected to Oracle</br>";
oci_close($conn);
}
else { echo "NOT Connected</br>"; }
?>

所以，奇怪的是，在这个例子中，上面的测试脚本不起作用，当它包含"initial .php"这使得连接和$conn变量，不会产生分段错误。

这不是很奇怪吗?还是我完全没注意到?

有更多调试的脚本:

<?php
ini_set('display_errors', 1);
error_reporting(E_ALL);
$conn = null;
echo "test oci</br>";
try {
$dbstr = "(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521 )) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = svc) ))";
$conn = oci_pconnect('user', 'pw', $dbstr) or die (ocierror());
if ($conn) {
echo "Connected to Oracle</br>";
}
}
catch (Exception $ex) {
echo $ex->getMessage();
$e=oci_error();
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
echo 'failed to connect to Oracle DB: ' . $e['message'];
}
finally {
if ($conn) { oci_close($conn);
echo "Connected closed.</br>";
}
}
?>
