I checked the FD information with the command "ls -l /proc/25977/fd"  // here 25977 is Qemu process. I found that the creation timestamp of  the FD was not changed, but the socket information to which the FD was linked was changed.
So, I guess the FD is reused when establishing new tcp connection.

I alomost got a lot of tcp connections from host mounted with block devices to ceph's backend.
