You'll note in your top display that you have a lot of memory in your buffer and cache pools. This is actually free memory and will be reclaimed if it's needed. Looking at the "free" number doesn't show you the whole picture - the kernel is using memory efficiently and leaves it in a pool where it might be pulled more efficiently rather than moving it to the free pool. In summary, free = free + buff + cache -- Ed Wilts, Mounds View, MN, USA mailto:ewilts@xxxxxxxxxx Member #1, Red Hat Community Ambassador Program -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
