Morning all ... Okay, according to my logs, here is what I have: Aug 31 22:13:47 venus scrappy[35952]: Starting KVM Monitoring Aug 31 22:13:47 venus scrappy[35962]: kernel_vm_end: 0xf6400000 Aug 31 23:00:03 venus scrappy[41669]: kernel_vm_end: 0xf6800000 Sep 1 00:00:25 venus scrappy[50135]: kernel_vm_end: 0xf7000000 Note that I modified my script so that it only reports to syslog when the value changes, instead of every minute ... On the other server, she's still running with: Sep 1 02:05:30 jupiter root[93918]: kernel_vm_end: 0xfa000000 Sep 1 02:07:32 jupiter root[95929]: kernel_vm_end: 0xfa400000 Sep 1 02:09:34 jupiter root[98699]: kernel_vm_end: 0xfa800000 Sep 1 02:10:34 jupiter root[1076]: kernel_vm_end: 0xfac00000 Sep 1 04:30:42 jupiter root[33295]: kernel_vm_end: 0xfb000000 Both server(s) are running kernels updated to sources of last night.
