We've even seen out of memory errors on postgres logs a few times when the server is just using something like 8GB out of 128GB of ram
Has anyone experienced a similar issue or have seen weird memory usage patrons with CentOS 7?
Any chance zone reclaim mode is enabled?cat /proc/sys/vm/zone_reclaim_mode
