> Issue Type: Bug
> Components: guacamole
> Affects Versions: 1.6.0
> Reporter: rysinal
> Priority: Major
>
> When using the Docker image of guacd (v1.6.0) as an RDP gateway, I
> intermittently encounter frame error issues. The issue is resolved after
> restarting the guacd container, but it reoccurs after some time. RDP
> connections fail intermittently, and the system kernel logs are roughly of
> the following type:
> {code:java}

> {"log":"guacd[635479]: DEBUG:\u0009SSL_CTX_new

> {code}
> Based on the information searched using the log details, I have also tried
> recompiling the guacd image. The Dockerfile uses debian:bookworm-slim as the
> base image, yet the problem still occurs after a period of time. Please help
> verify and resolve this issue.
