as implied in the first email ( below ) , the only thing that I see as different between this particular process and any other is that a) the executable is 8.5 megs as it sits on the disk b) the executable has at least 10 threads in it.

Michael -- michael.schus...@oracle.com http://blogs.sun.com/recursion ++++++++++++++++++++++++++++++++++++ I have a very simple dtrace script ( shown below ). This script works on simple programs just fine. Now I want to use this script on a large C++ executable. The executable is 8.5 meg in size on a x86 platform. This executable has more than 10 threads in it. I try to execute that the dtrace script and I get this error - ./adc.d 24930 dtrace: failed to compile script ./adc.d: line 7: failed to grab process 24930 What is the error really trying to tell me ? wr ####################### #!/usr/sbin/dtrace -qs BEGIN { flag = 1 ; } END { flag = 0 ; } pid$1:::entry { self->t[probefunc] = timestamp ; } pid$1:::return /self->t[probefunc] && flag / { this->time = timestamp - self->t[probefunc] ; @[probefunc] = avg(this->time) ; self->t[probefunc] = 0 ; } _______________________________________________ dtrace-discuss mailing list dtrace-discuss@opensolaris.org
