Subject: Validation: Error reading assumed real value

Hi,
Once a day I check memory usage of cf-execd. It's restarted if the usage is
above a
fixed limit. The code works and restarts the process if you lower the
cfexecd_max_mem
value.
I get this mailed to me at 01 AM. I saw this in an earlier post.
Validation: Error reading assumed real value 7112
1520 (anomalous remainder 1520)

The rss column value of cf-execd is 7112.
Here is the code I use. I had problem with process parsing in Solaris so I went
with
ps/pkill/pgrep until this feature is fixed.
bundle common g

vars:
solaris::
"workdir" string => "/var/cfengine";
"cfexecd" string => "$(g.workdir)/bin/cf-execd";

"ps" string => "/usr/bin/ps";

"zone_name" string => execresult("$(g.zonename)","noshell");
"cfexecd_max_mem" string => "8000";
"cfserverd_max_mem" string => "7000";
}

"memory_leak" expression =>

classes => if_repaired("start_cfexecd");
start_cfexecd|!cfexecd_started::
"$(g.cfexecd)",
classes => if_repaired("cfexecd_started");
}
Do you see any errors in my code or have I hit a feature?
I use community version 3.1.4.
