    Hello - I am trying to access the article mentioned in the thread ...
    https://ca-broadcom.wolkenservicedesk.com/external/article?articleId=15374
    ... but it seems it is not accessible any more.

    Can someone shed some light on what are the variables i can use to clear connections to the SSH pools?

    Thanks.

    What version of gateway are you. There are new cluster properties in the later versions of 9.x that help cleanup the pool. Instead of just the max active which increases its size. But the better use case for ssh assertion is much strong in 9.4.

    Also if this is something that happens after a little while you can temporarily re-claim the pool (if its on inbound connect) by disabling / enabling the ssh listen port on the gateway.
