This happens due to intensive I/O. You need to change swapiness and other parameters.
Issue this commands as root:
Code:
echo 30 > /proc/sys/vm/swappiness
echo 0 > /proc/sys/vm/page-cluster
echo 512 > /sys/block/mmcblk0/queue/nr_requests
echo 512 > /sys/block/mmcblk1/queue/nr_requests
echo 0 > /sys/block/mmcblk0/queue/iosched/slice_idle
echo 0 > /sys/block/mmcblk1/queue/iosched/slice_idle
echo 32 > /sys/block/mmcblk0/queue/iosched/quantum
echo 32 > /sys/block/mmcblk1/queue/iosched/quantum
echo 80 > /sys/block/mmcblk0/queue/iosched/fifo_expire_sync
echo 80 > /sys/block/mmcblk1/queue/iosched/fifo_expire_sync
echo 180 > /sys/block/mmcblk0/queue/iosched/fifo_expire_async
