主机: IBM,9179-MHB
OS: 5300-11-05-1036
现象: 系统登陆很慢,使用topas看到lo0接口的流量很大,察看errpt,发现没有任何能影响系统响应的错误,但是发现了系统内核跟踪工具trace,
IBM的内核跟踪工具,只有使用 trcstop 杀掉该进程,以前电信出现过,今天重温一下 :)
刚开始使用kill尝试多次都杀不掉该进程,后man察看trace
man trace
-a
Runs the trace daemon asynchronously (i.e. as a background task). Once trace has been started this way, you can use
the trcon, trcoff, and commands to respectively start tracing, stop tracing, or exit the trace session. These
commands are implemented as links to trace.
使用trcstop终于kill掉该进程,系统速度也有明显改善
