系统突然宕机，提示如下
"OpenServer 5.0.6 with SMP and Devsys installed panics when I use the trace(CP) utility to trace system calls of a command. For example, when I type "trace route" the system panics with the message
              PANIC: pswtch: can't while owning a lock
The same panic may occur when using process tracing inside a debugger.  
Solution
This problem has been reported to SCO Engineering and is fixed in the upcoming release of OpenServer 5. "
请各位大侠分析宕机原因。谢谢
