I have also encounter similar problem. Except that under “memory map” I got something like this:

08048000-0808f000 r-xp 00000000 fd:01 131867 /usr/sbin/sshd (deleted)
0808f000-08090000 r--p 00046000 fd:01 131867 /usr/sbin/sshd (deleted)
08090000-08091000 rw-p 00047000 fd:01 131867 /usr/sbin/sshd (deleted)

I have also read the StackOverflow post (reinstall openssh-server) mentioned by @kamaln7 before, and it didn’t solve my problem. However, after that, I decided to restart the whole VPS which solved my problem.

@aemamdouh @andyhaolly according to this StackOverflow post, they were able to fix it by following the instructions here. Give that a shot and let me know if it works! :)
