Column	Runaways
Source	/usr/bin/prstat
Description	The list of processes that are suspected of being a runaway. The test first calculates how much CPU load prstat shows when a single CPU is 100% busy. This calculation is done as follows: If you have a 12 CPU box, then 1/12 is a 100% load for a single CPU.  So, prstat will show 12.5% if a process is consuming the entire CPU. Here are some other numbers indicating 100% consumption of a CPU. 2 cpus 50.0% 8 cpus 12.5% 12 cpus 8.33% 24 cpus 4.17% The current logic looks for processes that are consuming >90% of a CPU and have accumulated at least 30 minutes of CPU time. For example, on an 8 cpu box we suspect programs that are 90% of 12.5% or show > 11.25%. Common processes that enter the runaway state are netscape 4.79, netscape 7.0, mozilla 1.2.1, acroread, _progress (bugtraq database), java_vm, jre, and Xsun.
