Kernel core file not generate if the disk space is less than RAM size

Hi Checkmate !!!

I come across to know that If device does not have sufficient disk space to create kernel core files in case of a kernel crash the RAM memory is dumped to the /var/log partition. If there is no sufficient disk space available a core dump will not be created.

So minimal free disk space in /var/log partition should be equal or greater than the RAM memory size

Example : Device Total RAM: 128768MB Available disk space in /var/log: 70354 MB so in this kernel crash file will not generate

So I just to know that what about kernel crash the RAM memory ?

And what about on other case if the coredump size is below 1 GB or like below RAM memory size ?

Pls suggest

kernel core dump only dumps kernel memory, AFAIK, and not all RAM. Do you have any error message for the case you describe? If your kernel dump enabled?

@_Val_  Thanks for the update.

One of our customer having Check pro service where we see this warning mentions on the pro report.

I need more information to confirm on this so accordingly we will mention the ratio.
