Hello there I run and openvz based system for 14days now. Yesterday this starts : [root]# Nov 29 10:06:30 MYSYS kernel: Negative vm_rss: process pid 20999 comm avbasestest flags 4, vma e35c76f4 b7b26000-b7b43000 00000000 rss 1 freed 29 Nov 29 10:06:30 MYSYS kernel: flags 100075, ub 221 Nov 29 10:06:30 MYSYS kernel: [<c016966f>] warn_bad_zap+0xff/0x120 Nov 29 10:06:30 MYSYS kernel: [<c0169764>] unmap_page_range+0xd4/0xf0 Nov 29 10:06:30 MYSYS kernel: [<c01698a0>] unmap_vmas+0x120/0x250 Nov 29 10:06:30 MYSYS kernel: [<c016f601>] exit_mmap+0xa1/0x1a0 Nov 29 10:06:30 MYSYS kernel: [<c0128cd0>] mmput+0x60/0xb0 Nov 29 10:06:30 MYSYS kernel: [<c012efe1>] do_exit+0x181/0x560 Nov 29 10:06:30 MYSYS kernel: [<c012f4a0>] do_group_exit+0x40/0xb0 Nov 29 10:06:30 MYSYS kernel: [<c04d93e3>] syscall_call+0x7/0xb Now the system crashed all vm's. Only a reboot of the hardwarenode was helpfull. This is reproduceable while updateing aveserver-signatures. HW-Node is running RH-Enterprise 4 2.6.9-023stab032.1-smp #1 SMP VPS is running debian-sarge. Can you give me hint what causes this crash. Best rema.

Hello, This is a known bug, it is fixed in 2.6.9-023stab034.1, which is not released yet. However, this is the minor bug, so you can work smoothly with it before the new stable kernel will be released. HTH, Vasily.
Tnx for your awnser. I switch to 2.6.18-ovz028test005.1 so this should by happen again. (i hope) Best Rene
Can you try 036.1 kernel which is to be released soon? I uploaded it for you here: http://download.openvz.org/~dev/023stab036.1/
tnx for this hint. best rema
