FS ocfs2 - why is the second node being rebooted?

Question

linux

There is a shelf connected via iscsi to two servers. On the connected capacity, the OCFS2 FS is formatted and mounted to two servers:

[[email protected] ~]$ sudo cat /etc/ocfs2/cluster.conf
node:
        ip_port = 7000
        ip_address = 192.168.99.1
        number = 0
        name = redhat1
        cluster = ocfs2
node:
        ip_port = 7000
        ip_address = 192.168.99.2
        number = 1
        name = redhat2
        cluster = ocfs2

cluster:
        node_count = 2
        name = ocfs2

O2CB parameters:

[[email protected] ~]$ grep -v "#" /etc/sysconfig/o2cb
O2CB_ENABLED=true
O2CB_STACK=o2cb
O2CB_BOOTCLUSTER=ocfs2
O2CB_HEARTBEAT_THRESHOLD=151
O2CB_IDLE_TIMEOUT_MS=30000
O2CB_KEEPALIVE_DELAY_MS=5000
O2CB_RECONNECT_DELAY_MS=2000

In case of failures on one node, for example, a power outage or a kernel panic, the second node is rebooted. Why is this happening? how to avoid it?

Maybe it's a kernel configuration issue.
