Hi Nick, Hi Alex,
@Nick
/"I've got a very similar environnent (guacd 1.5.5 on CentOS 7), and

been made with it and I've not seen this issue."/
The Problem was for me only on *concurrent connections*. I'm running
also the 1.5.5 (docker) on our two guacamole (Loadbalanced) Hosts since
some month without problems. but with this 2 hosts we don't hit the 60
concurrent connection limit at the moment.
Maybe i can try to do a test on another standby host that is using 1.6
and connect via some servers to 60 hosts at the same time.

Hello Julian,
Thank you for your suggestion. My problem is indeed very similar
to the link you provided. I also found this bug link
https://issues.apache.org/jira/browse/GUACAMOLE-1998. It seems
that it has not been solved yet. I found two solutions from these
two links:
1. Use version 1.5.3;
2. Build guacd image based on Debian 12.
I think I can try to roll back to version 1.5.3 first.
What version of guacd are you running when you encounter this?
Part of the challenge with the issue linked above is that we've been
unable to reproduce the issue reliably - I've got a very similar
environnent (guacd 1.5.5 on CentOS 7), and it's been running for
several weeks with hundreds of connections having been made with it
and I've not seen this issue. There must be some other factor
contributing to producing this behavior, we just haven't figured that
out, yet.
