我正在尝试在centos7.6上使用docker安装openproject，但Phusion passenger在安装后无法启动。错误表明它无法解析响应。
The preloader process sent an unparseable response:。我不知道如何解决此问题。

日志中的导入行是这一行：
App 439输出：/app/vendor/bundle/ruby/2.6.0/gems/passenger-6.0.1/src/ruby_supportlib/phusion_passenger/preloader_shared_helpers.rb:108：在'fork'中：无法分配内存-fork （2）（Errno :: ENOMEM）
这意味着您的容器无法分配必要的内存。可能是因为您的系统处于OOM状态并且正在杀死某些事物，或者是由于守护程序的其他限制而导致它无法分配额外的内存
