【中文标题】RabbitMQ/Erlang 崩溃：无法重新分配 313760 字节的内存（“代码”类型）【英文标题】：RabbitMQ/Erlang crashing: Cannot reallocate 313760 bytes of memory (of type "code") 【发布时间】：2017-04-29 11:34:08 【问题描述】：谁能帮助理解这些崩溃日志？
RabbitMQ 3.6.6，Erlang 19.1 RabbitMQ 在 Microsoft Windows Web Server 2008 R2 6.1.7601 Service Pack 1 Build 7601 64bit 上运行。
RabbitMQ 在运行正常大约一年后昨天开始崩溃。现在我已将 Erlang 和 RabbitMQ 服务器升级到上述版本，但这并没有改变任何东西 - 仍然崩溃 经常。

我也找到了 Erlang 崩溃转储，请参阅 HERE
如果有更多信息需要我提供，请告诉我。 谢谢！
【问题讨论】：
【参考方案1】：
** eacces,[erlang,open_port,
[spawn,"C:\\Windows\\system32\\cmd.exe /c dir /-C /W \"d:/ETOIMI~1/RabbitMQ/RABBIT~1\"",
eacces 是一个Erlang error：
eacces 缺少父目录的搜索或写入权限 目录。
很可能该服务在此处无法访问：d:/ETOIMI~1/RabbitMQ/RABBIT~1\
【讨论】：
好吧，因为在崩溃开始之前权限没有改变，感觉不太可能。但是对于任何情况，我都为每个人添加了完全控制权。 RabbitMQ 继续崩溃。现在我注意到，在同一台机器上运行的其他一些应用程序恰好在 RabbitMQ 崩溃之前占用了所有 RAM。使其他应用程序脱机，到目前为止没有崩溃...此外，当您检查 Erlang 转储时，有一行：Slogan: eheap_alloc: Cannot allocate 2545496 bytes of memory (of type "heap").以上是关于RabbitMQ/Erlang 崩溃：无法重新分配 313760 字节的内存（“代码”类型）的主要内容，如果未能解决你的问题，请参考以下文章
