Syslog recorded a kernel problem: Mar 2 10:36:27 host5 kernel: Unable to handle kernel NULL pointer dereference at 0000000000000232 RIP: Mar 2 10:36:27 host5 kernel: <ffffffff802ba089>{inet_sendmsg+23} Mar 2 10:36:27 host5 kernel: PGD 0 Mar 2 10:36:27 host5 kernel: Oops: 0000 [1] SMP Mar 2 10:36:27 host5 kernel: last sysfs file: /class/iscsi_connection/connection22:0/exp_statsn Mar 2 10:36:27 host5 kernel: CPU 3 [...] The problem happened in a XEN configuration (Domain0). Reproducible: Sometimes Steps to Reproduce: 1. Configure iSCSI targets on multiple hosts Actual Results: Occasionally things don't work. The machine needs a reboot to recover. Expected Results: Bad things should not happen (i.e. a reboot of the machine should be avoidable) I'll attach the relevant part of the syslog and a decoded Oops. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
