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 atapci1@pci0:0:31:2: class=3D0x010601 card=3D0x778015d9 chip=3D0x27c1808= 6 rev=3D0x01 hdr=3D0x00 vendor =3D 'Intel Corporation' device =3D '82801GB I/O Controller Hub SATA cc=3DAHCI' class =3D mass storage subclass =3D SATA Mar 14 22:45:37 top kernel: atapci1: <Intel AHCI controller> port 0x6898-0x= 689f,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 p= orts 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] =20 Mar 14 22:45:37 top kernel: ad4: 381554MB <Seagate ST3400620NS 3.AEG> at at= a2-master SATA300 Mar 14 22:45:37 top kernel: ad6: 381554MB <Seagate ST3400620NS 3.AEG> at at= a3-master SATA300 =3D=3D What happened =3D=3D 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=20 couple of hours. I didn't have had any crashes since then but don't=20 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.
