You also told me that this machine had no swap enabled, which is an
unusual configuration and restricts the ability of the VM to defragment
memory.  I would recommend adding a small swap file/partition.  However:

This particular allocation is for an array which is not used for DMA and
therefore could be stored in non-contiguous pages allocated with
vmalloc().  But there may be some good reason not to do this.
