I have a node.js process running on a Solaris box. In the top command view, the "RES" column which I guess represents the physical memory is constant and reasonable. However the "SIZE" column keeps growing, within two hours it could reach up to 520MB and is constantly going up.
- What does the "SIZE" column exactly represent?
- Is this behavior acceptable (normal).
- Would restarting the process have any effect on performance (e.g. loose cached resources, etc.) ?
