Thanks Eric, > Looks like an oops/panic/BUG - but are you sure you didn't start copying a line or two too late? Well, there are other interesting information in /var/log/messages about 10 minutes I uploaded them here http://vam-emp.aschendorff.de/tmp/ We also suffered from a huge amount from these log entries they are somehow related to disabling ipv6 and vsftp but I guess this is not really related to our ext4 crashes. After now upgrading vsftp they disappeared, debian has got a bug for that http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=590653 Jan 18 20:52:26 ez-nfs-prod-vm1 kernel: [14913.361952] lo: Disabled Privacy Extensions Thanks -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
