Has the kernel parameter 'kernel.panic_on_oops' always default been set to 1 in Red Hat Enterprise Linux?
Environment
- Red Hat Enterprise Linux (RHEL) 6
Issue
- In a minimal install we noticed that:
- kernel.panic_on_oops = 1
- We had a problem with an oops that resulted unexpected in a kernel panic.
- Is there a specific reason why this is now the default?
Resolution
- The
kernel.panic_on_oopskernel parameter is default set to 1 since the official GA release of RHEL6
Root Cause
- This parameter has been set to 1 to obtain the same behavior as previous RHEL releases like RHEL5
Diagnostic Steps
- Use
sysctlto check the current value of this parameter
$ sysctl kernel.panic_on_oops
1
