Think the point here is that the original 5K VM only had 3 Gbytes of swap space. subsequent VMs had 6Gbytes by default. TAC are just upgrading the swap to what the new "standard" VM has.
Our 100% cpu issue went away after increasing the swap space.
Having said that, I'm stil a bit confused at swap space usage on a clearpas VM. WE have 2 * C3000 VMs running on deficated ESX servers with 2 * the recommended harware spec for a C3000. They've got 64Gbytes of memory and 2 Gbytes of swap space. .. and are newly built 6.7.9 VMs ( 6.7.0 -> 6.7.9) .They aren't heavily loaded to say the least yet one of them has 53Gbytes ram free and is using 1.3 Gbytes out of its 2 G swap space. I would have expected it to use 0 of swap given the amount of memory like the other ones.
