CentOS 上的 ps 段错误

我有一台 CentOS- 5.5 服务器，安装了来自 epel repo 的 python2.6（默认情况下禁用）。它不断出现分段错误。我还安装了来自 epel repo 的 maatkit。此外，我正在运行 percona 作为复制从属。我这里有 strace 的最后几行。（对于 pastebin 来说太长了）

stat("/proc/17774", {st_mode=S_IFDIR|0555, st_size=0, ...}) = 0
open("/proc/17774/stat", O_RDONLY)      = 6
read(6, "17774 (bash) S 17772 17774 17774"..., 1023) = 256
close(6)                                = 0
open("/proc/17774/status", O_RDONLY)    = 6
read(6, "Name:\tbash\nState:\tS (sleeping)\nS"..., 1023) = 753

不确定设备出了什么问题。

答案1

尝试重新挂载“/dev/pts”：

 mount -o remount /dev/pts

尝试以 root 身份运行 python。

还添加“mount”输出和python脚本/命令。
