I read through the kernel panic message line by line and it looks like the network driver is to blame. I see the page fault. I'm thinking that changing to another network card might resolve this situation. -Chris -----Original Message----- From: Holcombe, Christopher Sent: Sunday, January 20, 2013 7:35 PM To: target-devel@xxxxxxxxxxxxxxx Subject: kernel panic with target-utils Hi Everyone, I'm using kernel 3.8.0r3 with Ubuntu 12.10. I'm mounting ceph rbd devices and exporting the target over fibre channel with target-utils. I'm noticing under high load situations when the ceph cluster goes into recovery mode it sometimes causes the kernel on my proxy server to crash. If anyone has insight it would be much appreciated :-) Here's the dstat output I see just before it crashes: ----total-cpu-usage---- ---procs--- -dsk/total- ----interrupts--- --io/total- -net/bond0-
