/******************* Solution


If you do not restart the server, run the following command in Linux:
Echo never>/sys/kernel/mm/transparent_hugepage/enabled
Echo never>/sys/kernel/mm/transparent_hugepage/defrag




Effective immediately after server restart:
# Vi/etc/rc. local
If test-f/sys/kernel/mm/transparent_hugepage/enabled; then
Echo never>/sys/kernel/mm/transparent_hugepage/enabled
Fi
If test-f/sys/kernel/mm/transparent_hugepage/defrag; then
Echo never>/sys/kernel/mm/transparent_hugepage/defrag
Fi
