Now we have: - worker1: Trusty with Trusty kernel, no swapping - worker2: Utopic with Kernel 3.13.11-031311ckt14-generic, swapping - worker3: Utopic with Kernel 3.18.2-031802-generic, swapping So we still encounter the swapping problem with Utopic installations no matter, which kernel is installed - Trusty kernel - Kernel 3.13.11-031311ckt14-generic - Kernel 3.18.2-031802-generic Again my question: What can be different in Utopic installation causing this swapping kernel behavior?

Hmm, sorry. Downloaded file is stored in an XFS filesystem on a rotating disc partition.
