Disk is full but du (disk usage) does not give any clues which directory contains the data

I have a strange problem. My harddrive is according to df -h full:

$ df -h
Filesystem      Size  Used Avail Use% Mounted on
tmpfs           383M  1.1M  382M   1% /run
/dev/sda1        38G   36G     0 100% /
tmpfs           1.9G     0  1.9G   0% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
/dev/sda15      253M  1.1M  252M   1% /boot/efi
tmpfs           383M  4.0K  383M   1% /run/user/1000

But, when I want to check which directory is eating up how much space I get the following output:

$ sudo du -ahd 1 | sort -h
du: cannot access './proc/1204547/task/1204547/fd/4': No such file or directory
du: cannot access './proc/1204547/task/1204547/fdinfo/4': No such file or directory
du: cannot access './proc/1204547/fd/3': No such file or directory
du: cannot access './proc/1204547/fdinfo/3': No such file or directory

39M ./home
121M    ./boot
152M    ./opt
1.4G    ./snap
1.8G    ./var
2.1G    ./usr
5.6G    .

I am actually confused because I'd expect here to see the directory which contains all this data. But adding up the numbers does not yield 36GB of data.

What is going on here?

Yes it did. I had to restart a service on my machine and after that the memory was freed. Strange, never had this before....

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
