共享主机上的Composer内存已用尽

现在，共享FreeBSD主机上以前可以使用的沙箱现在无法运行composer更新或安装，并出现内存耗尽错误。昨天之前，我能够顺利奔跑php ./composer.phar update。我不认为需要更多的内存。我可以在Windows系统上更新项目，没有任何问题。除了内存大小以外，哪些变量会导致内存耗尽错误？

为了对此进行测试，我将... / vendor的内容和composer.lock文件移动到了另一个目录，然后运行php ./composer.phar install --prefer-dist。[Composer位于项目目录中，因此我可以在本地对其进行更新，而不是期望主机主机对其进行更新。]上面的命令导致：

% php ./composer.phar install --prefer-dist

编辑：可用内存：

编辑＃2，致命错误（使用作曲者1.1.0）继续存在，因为与上面的错误有所不同：
