Hi folks.[br][br]Ive installed CloudLinux a few days ago and faced a strange problem. [br]During high IO activity iowait is being too high and a lot of memory buffers are being used. When IO comes to its normal value OS doesn drop buffers so disk cache is too small.[br][br][br]This server is based at Centos 6.3 with ext4 at all partitions. As you can see at the attached images iowait was ok as well as memory buffers size before CloudLinux was installed.[br][br][img]http://i45.tinypic.com/4rryqc.png[/i...][br][br]Daily backup process is ran with root permissions and LVE 0 (root) has no CPU/IO limits.[br][br]Default config:[br]
[br][br]Memory limits are disabled and root user is allowed to use all 8 cores, 100% CPU, etc.[br]Please assist.
