Disk Usage sudden increase after exit-ing the browser

[absolutep]

1] Start Tribler.
2} Let it run for 20 minutes. Check disk usage.
3] Exit browser
4] Disk usage suddenly increases
5] Open tribler again and see same torrents operating with same leecher/seeders, therefore no reason for the spike in disk usage suddenly that too when exit-ing the browser and letting it run in system tray.

IMAGE 1 :- Tribler disk usage for some torrents when browser is open.

IMAGE 2 :- Sudden spike in disk usage as soon as browser is exit-ed.

CPU Usage has also increased significantly - close to 20% - does not happen when browser is open.

@absolutep nice stats! This is Bittorrent engine dumping the state of Torrents to disk. Especially seeding 20 GByte in 6 swarms would trigger a disk blast in Libtorrent for checkpoint saving. Also Tribler itself is also saving it's state to disk. We'll check if there is something going on.

Could be excessive disk writes due to a bug.
