Oracle 19c RAC; Oracle Linux UEK 8.8 (5.15.0-101.103.2.1.el8uek.x86_64);

After Enabling HugePages as recommended in MOS with large SGA 150G and PGA 40G (Server has 250G RAM) AND starting the Instance the Server freeze now and I only can power OFF/ON the system.

I've checked all things I found in MOS (disable transparent HugePages), run CVU checks and so on. But I've no idea yet.

I can start the Instance up to mount state. Then I see all SGA is in HP

=>cat /proc/meminfo

HugePages_Free:    5881

HugePages_Rsvd:    5370

HugePages_Surp:       0
