Hi Cascardo

As per SUSE document recommendation used 4096M crash kernel and with this value i have seen OOM traces during kdump.

root@woo:~# free -h
total used free shared buff/cache available
Mem: 251G 7.2G 243G 16M 567M 243G
Swap: 2.0G 0B 2.0G
root@woo:~# cat /proc/cmdline
root=UUID=df4c0331-9e6c-4592-9e0c-84f431ecb1f7 ro splash quiet crashkernel=4096M

Will try to increase to some more above 4096M and retry it.
