Subject: No space left on device after many files creation

I have found issue with ext4 partition.
I created many many empty files with the following way:
[cy6ergn0m@...achine heap]$ seq 1 10000000 | xargs touch

But this command crashes asfter a while with a error 'no space left on
device'. At the same time, df -h shows that I have 7Gb free on this file
system. So, I can't create any file in any directory at this filesystem.

[cy6ergn0m@...achine heap]$ pwd
/e4/sandbox/heap
[cy6ergn0m@...achine heap]$ ls -1 | wc -l
1261144
[cy6ergn0m@...achine heap]$ df -h /e4

[cy6ergn0m@...achine heap]$ touch ttt
