My server is: i7-4770 , 32 GB RAM,  FreeBSD 10.0-RELEASE-p7,  AMD64

Problem: Many processes (idle) are swapped - after few minutes normal working.

On old server - FBSD 9.1 with 16 GB with similar configurations (maybe some changes in login.conf for mysql i postgresql for more memory) & new version of some ports - there are not this problem.

Probably there are some problem with memory settings.
