I typically read this as "there's something non-trivial in the SEL"

The last line here is what caused the LED to blink. Disabling logging of 
events is considered bad enough.

So, you had a flood of correctable DRAM errors that caused the IPMI controller 
to give up logging them. Since it gave up you don't currently know if this 
behaviour has stopped (only happened then) or if it's continous.

If you clear the SEL (ipmitool sel clear) then errors will be able to be 
logged again and you can determine if it's indeed bad enough need further 
diagnostics/replacements (clearing the SEL also stops the blinking LED).
