Hi, by accident I observed that various CPU on a rather heavily loaded Oracle server sometimes consumed 100% sys

PID USERNAME USR SYS TRP TFL DFL LCK SLP LAT VCX ICX SCL SIG PROCESS/LWPID [b] 2889 root 0.0 100 0.0 0.0 0.0 0.0 0.0 0.0 0 0 0 0 prstat/1[/b] My question is if this is something to worry about or just works as expected? I would like to know because when there is problem it is very common for people to start multiple prstat/top etc. to try to see what's going on and that behaviour worries me more than a single instance of a prstat running. //Mike -- This message posted from opensolaris.org _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
