ubuntu - 如何调试崩溃的 memcached？

Question

我使用“/usr/bin/memcached -m 128 -p 11211 -U”启动了 memcached
11211 > memcached.log 2>&1 &"。我在 ec2 ubuntu 11 上运行它。
它只是崩溃而没有任何警告或登录到控制台或文件。

我从哪里开始调试呢？

编辑:我使用 -vvv 运行 memcached 并将其放在日志文件的末尾。 memcached 几乎没有发出大约 10 个请求就死了。

usr/bin/内存缓存调试 -m 128 -p 11211 -U 11211 > memcached.log 2>&1 &

如果你有它。如果没有，您可以从源代码构建它。此外，尝试将 strace 附加到该过程(假设这种情况反复发生)。
