Sometimes (very rarely), when I perform an lvm command, my server (which is a Xen Dom0) will crash (But still respond to ping), and dmseg is flooded with Uhhuh. NMI received. Dazed and confused, but trying to continue You probably have a hardware problem with your RAM chips For me, this has happened when doing lvremove, and lvcreate My system details are as follows: Linux server.mydomain 2.6.18-194.32.1.el5xen #1 SMP Wed Jan 5 18:44:24 EST 2011 x86_64 x86_64 x86_64 GNU/Linux Xen version is 3.4.3 This issue is very rare, and has only happened to me maybe 3 times over the past 7 months, each time being when I issued an LVM command Has anybody experienced this before? Thanks </body> </html>
