The counts should add up to 100 - according to page 38 at http://developers.sun.com/solaris/articles/solaris_performanceandtools_ch3_processes.pdf [i]3.2.2 Process Microstates: prstat -m The process microstates can be very useful to help identify why a process or thread is performing suboptimally

This makes sense, however, I am still a bit confused. You are stating that in Solaris 9 microstate accounting gets only updated when the lwp is transitions from one state to another. So, if the process was idle for a long time (idle since before microstate accounting was started by prstat -m ??)
