Subject: process matching rsize not working as expected

To combat the current memory leaks I created a promise to kill cf3 procs if
they use too much memory. This seems to work fine on Linux hosts but triggers
unexpectedly on Solaris hosts.
bash-3.00# !ps
ps -eo rss,args|grep cf-
5488 /var/cfengine/bin/cf-monitord
2984 /var/cfengine/bin/cf-serverd
1368 grep cf-
2736 /var/cfengine/bin/cf-execd
It is my understanding that the above numbers are in kilobytes. Below is the
policy. So the current processes are below the limits. Yet when I run this
bundle the processes are killed. Have I made an error?
bash-3.00# cf-agent -Ib monitor
