Horizon api loses session info: see active desktop of another user

I see this behaviour in a pooled Linux Install, with RHEL 7.8:

Sometimes I get a desktop with an already logged in user or a session with a running "screensaver"

by some user.

I found out, that "horizon" loses the information, that the host is in use. (disconneted or active)

I'm using:

- VMware-horizonagent-linux-x86_64-7.9.0-13916467

And I have host1,..,hostN in the pool.

On the horizon server I can use the horizon admin API

with this I can check which sessions are in use by "user1"

If I enter some the username "user1" the api shows:

- no active/disconneted sessions for user1 (it shows no session)

Now, when I connect with the the horizon client I get a logged session by user1 on hostX

My conclusion:

Some horizon component loses the information that the host is in use and serves

a still running desktop environment/session as "available"

I wrote a python script, which gets the active session in the pool:

- who | grep tty | cut -d " " -f 1 | sort -u

- and compares this with the state of the horizon api.

I can see, that this scenario is not uncommon.

Question:

- Is this already fixed?
