如何调试崩溃的memcached？

Question

我使用“/ usr/bin/memcached -m 128 -p 11211 -U 11211> memcached.log 2> ”启动了memcached。我在ec2 ubuntu 11上运行它。 它只是崩溃没有任何警告或登录到控制台或文件。

我在哪里开始调试？

编辑：我用-vvv运行了memcached，并在日志文件的末尾得到了这个。 memcached几乎没有提出约10个请求并且死亡。

Answer 1

我忘记使用-d选项将其作为守护进程运行。一旦我添加它，崩溃消失了。疯狂我必须说。 @詹姆斯谢谢。

在/ usr/bin中/ memcached的-m 128 -vvv -p 11211-U 11211 -u Ubuntu的-d

USR /斌/ 分布式缓存调试 -m 128 -p 11211 11211 -U> memcached.log 2>

如果有的话。如果没有，你可以从源代码构建它。另外，尝试在流程中附加strace（假设这是重复发生的）。
