Question

有人可以帮助理解这些崩溃日志吗？

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OK一年后昨天开始崩溃。现在我已经将Erlang和RabbitMQ Server升级到上面提到的版本，但这并没有改变任何东西 - 仍然崩溃频繁。

.log中：

另外我发现了Erlang崩溃转储，请看 HERE

如果有更多信息需要我提供，请告诉我。谢谢！

** {eacces,[{erlang,open_port, [{spawn,"C:\\Windows\\system32\\cmd.exe /c dir /-C /W \"d:/ETOIMI~1/RabbitMQ/RABBIT~1\""},

eacces是Erlang error：

eacces缺少父目录的搜索或写入权限 Dir。

该服务很可能在此处访问时遇到问题：d:/ETOIMI~1/RabbitMQ/RABBIT~1\

RabbitMQ / Erlang崩溃：无法重新分配313760字节的内存（“代码”类型）
