First, I do understand that you want me to check for "the cause" and "the
outstanding growing malloc zones". 

Next I also do understand vmstat -z produces output related to zones, and
vmstat -m produces output related to types. 

You do not need to re-inform me of these ideas, but if you choose to again that
choice is out of my hands. I am not intending to frustrate you. :)

My unanswered questions are based on the idea that the two switches to vmstat
produce hundreds of different data points:

vmstat -z | wc -l
vmstat -z | wc -l

This is a lot of data (492 points) to check for changes. Naturally, I'd like to
reduce this check (which obviously has to be scripted) to data which is
With that, would you be so kind as to answer the following question?

Are you asking me to check each and every entry for each switch -m and -z to
vmstat to see what is growing OR is it possible to reduce the number of data
points to a specific useful subset? 

Thank you for your patience, as I am not a (modern) kernel dev.
