I also reported this in Mar 19th with some kgdb-output: http://lists.freebsd.org/pipermail/freebsd-stable/2009-March/048911.html == uname -a == FreeBSD top.uugrn.org 7.1-STABLE FreeBSD 7.1-STABLE #0: Sat Mar 14 20:06:04 CET 2009 r...@top.uugrn.org:/usr/obj/usr/src_RELENG_7/sys/TOP i386 == /usr/src/sys/i386/conf/TOP == include GENERIC ident TOP nodevice plip # TCP/IP over parallel == kldstat == Id Refs Address Size Name 1 9 0xc0400000 9ec994 kernel 2 1 0xc0ded000 164e8 geom_mirror.ko 3 1 0xc0e04000 6a45c acpi.ko 4 1 0xc5b9a000 e000 ipfw.ko 5 1 0xc5c94000 4000 logo_saver.ko 6 1 0xc5cf4000 4000 nullfs.ko 7 1 0xc5cfc000 4000 fdescfs.ko == Hardware == The machine ran about 30 months without crashes, at last with 6.4-RELEASE. The storage was on a 3ware with two attached SATA150 drives. Then we replaced the old 3ware + 2xSATA by two onboard-attached SATA300 drives with geom mirror configuration. The new OS is 7.1-STABLE from Mar 14th, which crashed with "vm_page_insert: page already inserted" under i/o load. geom mirror status: Name Status Components mirror/TOPRAID COMPLETE ad4 ad6 atap...@pci0:0:31:2: class=0x010601 card=0x778015d9 chip=0x27c18086 rev=0x01 hdr=0x00 vendor = 'Intel Corporation' device = '82801GB I/O Controller Hub SATA cc=AHCI' class = mass storage subclass = SATA Mar 14 22:45:37 top kernel: atapci1: <Intel AHCI controller> port 0x6898-0x689f,0x687c-0x687f,0x6890-0x6897,0x6878-0x687b,0x6880-0x688f mem 0xed000400-0xed0007ff irq 19 at device 31.2 on pci0 Mar 14 22:45:37 top kernel: atapci1: [ITHREAD] Mar 14 22:45:37 top kernel: atapci1: AHCI Version 01.10 controller with 4 ports detected Mar 14 22:45:37 top kernel: ata2: <ATA channel 0> on atapci1 Mar 14 22:45:37 top kernel: ata2: [ITHREAD] Mar 14 22:45:37 top kernel: ata3: <ATA channel 1> on atapci1 Mar 14 22:45:37 top kernel: ata3: [ITHREAD] Mar 14 22:45:37 top kernel: ad4: 381554MB <Seagate ST3400620NS 3.AEG> at ata2-master SATA300 Mar 14 22:45:37 top kernel: ad6: 381554MB <Seagate ST3400620NS 3.AEG> at ata3-master SATA300 == What happened == The crash happened while cvsupping from local cvsup-mirror, hence there was pretty much read-write i/o on the geom while having some CPU load. After rebooting the geom-mirror was degraded and rebuilded within some couple of hours. I didn't have had any crashes since then but don't want to provoke this since this server is kind of "productive". Maybe those "environmental" information does help someone to spot the cause of this error.
