On RHEL6 Transparent Hugepage kernel support is enabled by default.
This is known to cause sporadic crashes of Varnish.
It is recommended to disable transparent hugepages on affected systems. This
can be done with
``echo "never" > /sys/kernel/mm/redhat_transparent_hugepage/enabled`` (runtime) and changes to
`/etc/sysctl.conf` (persisted.)
It is recommended to disable transparent hugepages on affected
systems. This can be done with
``echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled``
(runtime) or by adding "transparent_hugepage=never" to the kernel boot
line in the "/etc/grub.conf" file (persistent).
On Debian/Ubuntu systems running 3.2 kernels the default value is "madvise" and
does not need to be changed.
