Hi, When running hte plockstat command as: pkockstat -s 10 -A -p PID# plockstat: failed to add to aggregate: Abort due to drop Does anyone know what this message probably mean? Thanks, Jenny -- Jenny Chen Software Engineer Market Development Engineering v-mail:(510) 574-7149 SUN Microsystems
Hi Jenny, This is probably due to a dynamic variable drop. Try adding -x dynvarsize=100m or larger. The -x option was added in Solaris 10 update 1 if memory serves. For a full list of options you can pass to plockstat (and dtrace and lockstat) via the -x option, check out the chaper in the DTrace manual on Options and Tunables: http://docs.sun.com/app/docs/doc/817-6223/6mlkidlis?a=view Adam On Wed, May 03, 2006 at 02:35:27PM -0700, Luojia Chen wrote:> Hi, > > When running hte plockstat command as: > > pkockstat -s 10 -A -p PID# > > plockstat: failed to add to aggregate: Abort due to drop > > Does anyone know what this message probably mean? > > > Thanks, > Jenny > > -- > > Jenny Chen > Software Engineer > Market Development Engineering > v-mail:(510) 574-7149 > SUN Microsystems > > > > _______________________________________________ > dtrace-discuss mailing list > dtrace-discuss at opensolaris.org-- Adam Leventhal, Solaris Kernel Development http://blogs.sun.com/ahl
Adam, Tried with "-x dynvarsize=100m", the error was still there unliess the "-A" option was removed. does it need to increase dynvarsize more?

Adam, What was the default size? Then I may increase it more accordly.

You may also need to tune aggsize.
