Had a similar issue on some CentOS servers and solved by changing the memory
overcommit  strategy of Linux kernel.
CentOS via its upstream sets /proc/sys/vm/overcommit_memory  to zero,
better to set il to 2 and play with /proc/sys/vm/overcommit_ratio (some say
that it should be 50, other 80)
Try to put this in /etc/sysctl.conf and see if anithing changes
vm.overcommit_memory = 2
vm.overcommit_ratio = 80
