SLES 11.3 运行系统命令时挂起

Question

我有一台运行 SLES 11 SP3 的 HP 服务器，有时会出现一些奇怪的问题。

每当您运行命令时，问题都与命令无关， .egps -ef等rcapache2 restart它启动命令， .eg 会输出一些内容，但是当它完成时，它实际上并没有完成并且卡住了，所以我不不回到提示。如果我然后按 CTRL+C 尝试杀死它，我会得到输出到 putty (SSH) 会话的字符，但它仍然不会退出。

我查看了 HP iLO 管理界面，但它没有报告任何故障。

感谢您的任何帮助，您可以提供。

shell 的 strace 输出

我对 strace 不太了解，但错误的文件描述符似乎盯着我看，但不确定是什么原因造成的。
