Here you go. It is kinda hard to catch the moment when the RAM is full, but the system is somehow responsive 
After some time it is almost unusable, but I can hear it infinitely swapping like mad 
I use 1999Mb of swap - on USB HDD.
I’m starting to think that this problem is somehow related to nextcloud… But not sure yet.
Any other logs would be useful?
If I uninstall lighttpd - everything become normal.
