 You can attach to existing process by using "ktrace -p <process id>".
 "ktrace" will write a file "ktrace.out" to the current directory
 afterwards. You can look at that file with "kdump" or "ktruss".

 That would probably help because you cannot be sure otherwise that
 you trace the right process. You could also try to instrument all
 the processes.
