If the size of any messages approach a quarter of the available RAM
(64Mb in your case) then the server will come under memory pressure. If
the queues stay fairly short and there are no other services installed
on the server then it should work, but you should test instead of
believing me. You may also want to configure sufficient swap space and
lower the vm_memory_high_watermark.
