Oracle Linux 6.4 Automatically Enables KDUMP - Can Cause Crashkernel Parameter Warning Message (Doc ID 1602529.1)

Last updated on MAY 26, 2021

Applies to:

Linux OS - Version Oracle Linux 6.4 and later
Oracle Cloud Infrastructure - Version N/A and later
Linux x86
Linux x86-64


 After installation of Oracle Linux 6.4 or later with UEK (Unbreakable Enterprise Kernel), the post-installation process invokes kdump configuration.

However, it invokes an alert:

Insufficient Memory to auto-enable kdump. Use system-config-kdump to configure manually

 Further, after reboot a warning message is written to the system log:

If system was upgraded from prior maintenance levels the above message appears where previously it didn't.

This is similar to the issue described in UEK: "kdump: No crashkernel parameter specified for running kernel" (Doc ID 1313194.1)


Installation of, or upgrade to, Oracle Linux 6.4 or later.
