[Bug 1886355] [NEW] glance upload image to rbd backend stuck

 

Public bug reported:

Uploading image to rbd backend stuck at saving state, and rbd du command
shows image size is not increasing, as well as ceph osd pool stats shows
that there is no client io.

a tcpdump shows the program is actually trying receive from client with
a rather small window size (which is 280 bytes) which is considerably
small compared to actual image size (35GB).
