It *is* not swapping, it *has moved* pages to swap in the past. These pages were never referred after that, so they remain in swap until they are accessed. > > Also, what would be the preffered way to see > exactly which processes do account for the swap usage? I don't think there's any way to track individual pages. But processes with a small resident set likely have pages in swap. > > Jan > > > > OpenBSD 5.2-current (GENERIC.MP) #2: Sun Sep 9 21:45:10 CEST 2012 > r...@biblio.stare.cz:/usr/src/sys/arch/macppc/compile/GENERIC.MP > real mem = 1073741824 (1024MB) > avail mem = 1032171520 (984MB) > mainbus0 at root: model PowerMac10,2 > cpu0 at mainbus0: 7447A (Revision 0x102): 1499 MHz: 512KB L2 cache > mem0 at mainbus0 > spdmem0 at mem0: 1GB DDR SDRAM non-parity PC3200CL3.0 > memc0 at mainbus0: uni-n > "hw-clock" at memc0 not configured > kiic0 at memc0 offset 0xf8001000 > iic0 at kiic0 > mpcpcibr0 at mainbus0 pci: uni-north, Revision 0xff > pci0 at mpcpcibr0 bus 0 > pchb0 at pci0 dev 11 function 0 "Apple UniNorth AGP" rev 0x00 > vgafb0 at pci0 dev 16 function 0 "ATI Radeon 9200" rev 0x01, mmio > wsdisplay0 at vgafb0 mux 1: console (std, vt100 emulation) > mpcpcibr1 at mainbus0 pci: uni-north, Revision 0x5 > pci1 at mpcpcibr1 bus 0 > pchb1 at pci1 dev 11 function 0 "Apple UniNorth PCI" rev 0x00 > bwi0 at pci1 dev 18 function 0 "Broadcom BCM4318" rev 0x02: irq 52, address > 00:11:24:bf:cb:2a > macobio0 at pci1 dev 23 function 0 "Apple Intrepid" rev 0x00 > openpic0 at macobio0 offset 0x40000: version 0x4614 feature 3f0302 LE > macgpio0 at macobio0 offset 0x50 > "modem-reset" at macgpio0 offset 0x1d not configured > "modem-power" at macgpio0 offset 0x1c not configured > macgpio1 at macgpio0 offset 0x9 irq 47 > "programmer-switch" at macgpio0 offset 0x11 not configured > "gpio5" at macgpio0 offset 0x6f not configured > "gpio6" at macgpio0 offset 0x70 not configured > "extint-gpio15" at macgpio0 offset 0x67 not configured > "escc-legacy" at macobio0 offset 0x12000 not configured > zsc0 at macobio0 offset 0x13000: irq 22,23 > zstty0 at zsc0 channel 0 > zstty1 at zsc0 channel 1 > aoa0 at macobio0 offset 0x10000: irq 30,1,2 > audio0 at aoa0 > "timer" at macobio0 offset 0x15000 not configured > adb0 at macobio0 offset 0x16000 irq 25: via-pmu, 0 targets > apm0 at adb0: battery flags 0x0, 0% charged > piic0 at adb0 > iic1 at piic0 > maxtmp0 at iic1 addr 0xc8: max6642 > kiic1 at macobio0 offset 0x18000 > iic2 at kiic1 > wdc0 at macobio0 offset 0x20000 irq 24: DMA > ohci0 at pci1 dev 24 function 0 "Apple Intrepid USB" rev 0x00: couldn't map > interrupt > ohci1 at pci1 dev 25 function 0 "Apple Intrepid USB" rev 0x00: couldn't map > interrupt > ohci2 at pci1 dev 26 function 0 "Apple Intrepid USB" rev 0x00: irq 29, > version 1.0, legacy support > ohci3 at pci1 dev 27 function 0 "NEC USB" rev 0x43: irq 63, version 1.0 > ohci4 at pci1 dev 27 function 1 "NEC USB" rev 0x43: irq 63, version 1.0 > ehci0 at pci1 dev 27 function 2 "NEC USB" rev 0x04: irq 63 > usb0 at ehci0: USB revision 2.0 > uhub0 at usb0 "NEC EHCI root hub" rev 2.00/1.00 addr 1 > usb1 at ohci2: USB revision 1.0 > uhub1 at usb1 "Apple OHCI root hub" rev 1.00/1.00 addr 1 > usb2 at ohci3: USB revision 1.0 > uhub2 at usb2 "NEC OHCI root hub" rev 1.00/1.00 addr 1 > usb3 at ohci4: USB revision 1.0 > uhub3 at usb3 "NEC OHCI root hub" rev 1.00/1.00 addr 1 > mpcpcibr2 at mainbus0 pci: uni-north, Revision 0x6 > pci2 at mpcpcibr2 bus 0 > pchb2 at pci2 dev 11 function 0 "Apple UniNorth PCI" rev 0x00 > kauaiata0 at pci2 dev 13 function 0 "Apple Intrepid ATA" rev 0x00 > wdc1 at kauaiata0 irq 39: DMA > atapiscsi0 at wdc1 channel 0 drive 0 > scsibus0 at atapiscsi0: 2 targets > cd0 at scsibus0 targ 0 lun 0: <MATSHITA, DVD-R UJ-825, DAND> ATAPI 5/cdrom > removable > wd0 at wdc1 channel 0 drive 1: <ST9808211A> > wd0: 16-sector PIO, LBA, 76319MB, 156301488 sectors > cd0(wdc1:0:0): using PIO mode 4, DMA mode 2, Ultra-DMA mode 4 > wd0(wdc1:0:1): using PIO mode 4, DMA mode 2, Ultra-DMA mode 4 > "Apple UniNorth Firewire" rev 0x81 at pci2 dev 14 function 0 not configured > gem0 at pci2 dev 15 function 0 "Apple Uni-N2 GMAC" rev 0x80: irq 41, address > 00:14:51:17:42:34 > bmtphy0 at gem0 phy 0: BCM5221 100baseTX PHY, rev. 4 > umass0 at uhub0 port 2 configuration 1 interface 0 "JMicron USB to ATA/ATAPI > Bridge" rev 2.00/1.00 addr 2 > umass0: using SCSI over Bulk-Only > scsibus1 at umass0: 2 targets, initiator 0 > sd0 at scsibus1 targ 1 lun 0: <SAMSUNG, HM251JJ, > SCSI2 0/direct fixed > serial.152d233919D0105140FF > sd0: 238475MB, 512 bytes/sector, 488397168 sectors > uhidev0 at uhub1 port 1 configuration 1 interface 0 "Apple Computer > HID-proxy" rev 2.00/19.65 addr 2 > uhidev0: iclass 3/1 > ukbd0 at uhidev0: 8 variable keys, 6 key codes > wskbd0 at ukbd0: console keyboard, using wsdisplay0 > uhidev1 at uhub1 port 1 configuration 1 interface 1 "Apple Computer > HID-proxy" rev 2.00/19.65 addr 2 > uhidev1: iclass 3/1 > ums0 at uhidev1: 5 buttons > wsmouse0 at ums0 mux 0 > vscsi0 at root > scsibus2 at vscsi0: 256 targets > softraid0 at root > scsibus3 at softraid0: 256 targets > bootpath: /pci@f4000000/ata-6@d/disk@1:/bsd > root on wd0a swap on wd0b dump on wd0b
