10 GBytes is tooooo much for a process and we want to know if there is anything we can do too solve this situation.
In general VIRT (virtual) is not the memory you should be looking at but the RES (resident) which is 4.7G and is the actual memory the process is using. You can cleary see it from:
Mem: 8125496k total, 5948512k used, 2176984k free
Eg your server has only 8Gb of physical ram and 2Gb free so there is no way a process can eat up "actual" 10 Gigs (unless Linux virtual memory). The bad thing though you have quite a large swap size and it's being used:
Swap: 14878048k total, 5731656k used, 9146392k free, 109640k cached
I would suggest to run: sysctl -w vm.swappiness=0 (and then set it in sysctl.conf for permanet use) so the systems avoids swapping as much as possible. p.s. to understand more about Linux memory management you might to look at this presentation https://www.youtube.com/watch?v=twQKAoq2OPE rr _______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx http://supercolony.gluster.org/mailman/listinfo/gluster-users
