/****************** Method of Solution


Do not restart the server in the case of a workaround that runs under 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
