Minimserver multiple instances on QNAP

[br@m]

First of all thanks for MinimServer software.

My question requires some background info:
- I run Minimserver on a QNAP NAS, installed with the regular QNAP package. This works fine.
- What I want to accomplish is to have 4 MinimServer instances (Jazz music, Classical music, Popular music, and MP3).
- I read that the regular QNAP package does not support installing multiple instances, so I sought for a work-around and decided to try using Docker instances.
- QNAP QTS 4.2 provides a utility ContainerStation which allows you to run Docker instances. I created a Docker instance with Minimserver and had it running succesfully. I run MinimWatch to manage the two, works fine. I use Linn Kazoo as a control app, also fine. So now I had two MinimServer instances running on the QNAP, all fine.
- As a next step, I created another Docker instance, with separate settings, so I would have three instances.
- This worked out fine initially until I ran into a problem I can't understand:

I created a second Docker instance with Minimserver, taking care to give each instance a unique displayname, and also unique settings for http and ohp ports. This worked fine and the third instance shows up in Minimwatch as expected. All maintenance functions in MinimWatch work fine, for all three instances.

However when in Kazoo, the two docker instances were conflicting, in such a way that Kazoo showed only one of the two, being the instance started first.

So apparently Kazoo cannot separate the two docker minimserver instances even though they have a different displayname and different port settings, while minimwatch has no problem at all.

I would really like to understand why Kazoo cannot separate these two instances, while MinimWatch can. Is there some other setting that confuses Kazoo?

Thank you for your reply
