Examine the parameters shown using the sysctl command relating to panic situations:
[root@WAYOUT etc]# sysctl a |grep panic |grep v hung
kernel.panic = 0
kernel.panic_on_oops = 0
kernel.softlockup_panic = 0
kernel.unknown_nmi_panic = 0
kernel.panic_on_unrecovered_nmi = 0
kernel.panic_on_io_nmi = 0
kernel.panic_on_oom = 2
[root@WAYOUT etc]# sysctl a |grep hung
kernel.hung_task_panic = 0
kernel.hung_task_chek_count 4194304
kernel.hung_task_timeout_secs = 120
kernel.hung_task_warnings = 10

The kernel panics if a kernel thread sleeps in the TASK_UNINTERRUPTABLE state for more than 120 seconds.

The kernel attempts to continue if a bug is encountered.

The kernel always panics if an out-of-memory condition arises.
