perl - OTRS PostmasterMailbox.pl 解析/MIME 类型

Question

从 Ubuntu Server 12.04 升级到 Ubuntu 14.04 LTS 后，我开始遇到解析问题
与我的 otrs 安装。
我使用 mysql 5.5 和 perl 5.18 运行 OTRS 3.1.1。
我认为这可能是因为我有一个旧的 OTRS 版本，所以请按照以下步骤操作
OTRS 手册决定升级到 OTRS 3.2.1、mysql 5.6 并将几乎所有的 perl 模块 + apache 升级到 2.4.7

我这样做了，一切正常，但解析问题仍然存在。
OTRS 通过 cronjob 使用脚本从邮箱中获取电子邮件并创建票证。
在许多票证上，它无法解析它们导致系统卡在特定邮件上
并连续打开同一张票，然后死掉(不解析队列中的其他邮件)。

有任何想法吗 ？

检查了 apache 日志，我得到了很多重新定义，如下所示:

Answer 1

您发布了很长的错误消息，主要是 perl 5.18 中正则表达式功能的折旧警告。

实际问题是这样的:

open body: Invalid argument at /opt/otrs/Kernel/cpan-lib/MIME/Entity.pm line 1872.

该问题也是由 Perl 5.18 中的更改引起的，并在 OTRS 3.2.12 中修复。您应该将您的 3.2.1 升级到 3.2.x 的最新补丁版本。
http://bugs.otrs.org/show_bug.cgi?id=9832

编辑:它也已在 3.3.1 中修复，因此如果您升级到最新的 3.3.x 补丁级别版本(即此时的 3.3.8)，您也可以!

顺便说一句，在后来的 3.2.x 版本中，正则表达式贬值警告也消失了!
