Hi. Kernel panic occurs because of the combination of cachefilesd and sendmail. Environment OS : CentOS 5 Kernel : CentOS 5 standard NFS Client : CentOS 5 i386 NFS Server : CentOS 5 i386 How To: 1, Stor OS image to NFS Server. I used CentOS 5. # mkdir /mnt/nfs # mount -t nfs -o fsc 192.168.1.1 /mnt/nfs # mkdir /mnt/nfs/centos5 # rsync -axv / /mnt/nfs/centos5 2, Launch sendmail. # /etc/init.d/sendmail stop <- if running # cd /mnt/nfs/centos5 # chroot . # /etc/init.d/sendmail start # exit (exit from chroot) 3, Connect to sendmail, and occur kernel panic. # telnet localhost smtp and occurs kernel panic. I want you to fix this problem. --- Daicon <daicon@xxxxxxxxxxx> -- Linux-cachefs mailing list Linux-cachefs@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cachefs
