Hi, Experts!

Please tell me what is the field named Couldfree
in the following output produced by vmstat -m

Memory statistics by bucket size

My problem:

I debug my own server application and worry about
correct memory usage.
I noticed that Couldfree value always grows at the computer
running my server program.
Is it dangerous?
