Sorry it took me so long. I am running a 64-bit processor and system and the outputs in order are: vmstat 7952 M total memory 7138 M used memory 3270 M active memory 1420 M inactive memory 813 M free memory 41 M buffer memory 2137 M swap cache 25461 M total swap 0 M used swap 25461 M free swap 37227 non-nice user cpu ticks 421 nice user cpu ticks 12315 system cpu ticks 493819 idle cpu ticks 12818 IO-wait cpu ticks 1 IRQ cpu ticks 68 softirq cpu ticks 0 stolen cpu ticks 2689813 pages paged in 87814 pages paged out 0 pages swapped in 0 pages swapped out 3632672 interrupts 10434409 CPU context switches 1417700784 boot time 5580 forks ps: nicolai 5336 36.3 24.1 4986112 1966940 pts/2 Rsl+ 15:07 2:37 ./KSP.x86_64 nicolai 5755 0.0 0.0 12580 1016 pts/3 S+ 15:14 0:00 grep --color=auto KSP proc status: Name: KSP.x86_64 State: S (sleeping) Tgid: 5336 Pid: 5336 PPid: 4760 TracerPid: 0 Uid: 1000 1000 1000 1000 Gid: 100 100 100 100 FDSize: 256 Groups: 100 482 VmPeak: 4987452 kB VmSize: 4986112 kB VmLck: 0 kB VmPin: 0 kB VmHWM: 1966940 kB VmRSS: 1966940 kB VmData: 4588720 kB VmStk: 472 kB VmExe: 19392 kB VmLib: 35556 kB VmPTE: 4984 kB VmSwap: 0 kB Threads: 18 SigQ: 0/63405 SigPnd: 0000000000000000 ShdPnd: 0000000000000000 SigBlk: 0000000000000000 SigIgn: 0000000000381000 SigCgt: 00000005a08004ec CapInh: 0000000000000000 CapPrm: 0000000000000000 CapEff: 0000000000000000 CapBnd: 0000001fffffffff Seccomp: 0 Cpus_allowed: c Cpus_allowed_list: 2-3 Mems_allowed: 00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000001 Mems_allowed_list: 0 voluntary_ctxt_switches: 132109 nonvoluntary_ctxt_switches: 512561 Additionally here is the mod loaders output: KSP: 0.25 (Unix) - Unity: 4.5.2f1 - OS: Linux 3.11 openSUSE project 13.1 64bit USI Tools - 0.2.4 B9 Aerospace - 5.2.6 CIT - CIT_Util - 1.1 CIT - KERT - 1.2.1 Community Resource Pack - 0.2.3 Ferram Aerospace Research - 0.14.4 Firespitter - 6.3.5 RasterPropMonitor - 0.18.3 KSP-AVC Plugin - 1.1.5 Kerbal Engineer Redux 1.0 - 1.0.11.3 KineTechAnimation - 1.1.1 ORSX - 0.1.3 ResGen - 0.28.2 TAC Fuel Balancer - 2.4.1.5 TAC Life Support - 0.10.1.13 MKS - 0.21.3 When swap does activate, it does so with no actual memory left slowing down KSP as well as my system by an unbearable amount. The Firespitter mod is far outdated,it came packaged with two 0.25 mods claiming that it works though.
