[Ocfs2-users] kernel panic - not syncing

[Consulente3]

Hi all, 

my test environment, is composed by 2 server with centos 4.4
nodes is exporting with aoe6-43 + vblade-14

kernel-2.6.9-42.0.3.EL
ocfs2-tools-1.2.2-1
ocfs2console-1.2.2-1
ocfs2-2.6.9-42.0.3.EL-1.2.3-1

/dev/etherd/e2.0 on /ocfs2 type ocfs2 (rw,_netdev,heartbeat=local)
/dev/etherd/e3.0 on /ocfs2_nfs type ocfs2 (rw,_netdev,heartbeat=local)

Device                FS     Nodes
/dev/etherd/e2.0      ocfs2  ocfs2, becks
/dev/etherd/e3.0      ocfs2  ocfs2, becks

Device                FS     UUID                                  Label

O2CB_HEARTBEAT_THRESHOLD=31

when i try to make stress test:

Index 4: took 0 ms to do checking slots

Kernel panic - not syncing: ocfs2 is very sorry to be fencing this
system by panicing


<6>o2net: connection to node ocfs2 (num 2) at 10.1.7.107:777 has been
idle for 10 seconds, shutting it down
(3,0): o2net_idle_timer:1309 here are some times that might help debug
the situation:
(tmr: 1169487957.71650 now 1169487967.69569 dr 1169487962.88883 adv
1169487957.71671:1159487957.71674
func 83bce37b2:505) 1169487901.984644:1169487901.984676)

the kernel panic occurs always on the same node, and the other node
still responding

thanks!
