So it looks like you are running into the race condition the 
lingering close is expected to solve.  You may want to upgrade 
nginx then.

Note well that lingering close support in HTTP/2 was added in 
nginx 1.19.1, more than two years ago, and the last nginx version 
without it is not supported for more than a year.
