Significant virtual memory paging was detected
From time to time, I do see the message from my tools and it said "Significant virtual memory paging was detected on the host operating system", the question is:
1. is it b/c the server is low on physical RAM so it has to use swap page? if so, it doesn't make any sense b/c I have plenty available RAM on the server that had not been used.
2. is it b/c SWAP size is bit small?
3. If none of the above, then what does the message really mean?
