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.

Do you see any errors in my code or have I hit a feature?

I use community version 3.1.4.
