Hi Mursel, >> However, when the user's session ends and we log back into the Ubuntu server, navigating to localhost:5000 shows that the service has stopped. "cluster manager" service you meant? What is the resource of that VM which has Cluster Manager? Any log in `clustermanager.log` ?

Yes, I meant the Cluster Manager service. The logs don't show any issues because the service stops. Could you clarify what you mean by 'resource'?

Hi, Mursel! resource means the VM capacity, like CPU, RAM, Disk Space, etc. Can you please share the `clustermanager.log`? Regards ~ Shakil

>> Ram: mem total: 3044104 kb >> Cpu: QEMU Virtual CPU version 2.5+ - Memory: 3 GB - CPU: 2 cores Do you have liberty to make it 8 GB memory and 4 cores CPU? >> Clustermgr.log Thanks, nothing about startup/stop here. Anything in celery.log ?

Hey Zico, I will let them know with the provided resources. The celery.log only contains modify operations so nothing about startup/stop. I will keep you updated when we have done the changes.

Hey Zico, 1) We have retested and observed that the Ubuntu server performs faster. However, we still notice that the cluster manager service stops when the RDP app is closed. Since the cluster manager is installed under a user account, we believe the service stops when the session ends. We are exploring ways to run the service independently of the user session. Do you have any insights on this issue? 2) We have another question. We have multiple environments for Gluu (dev, acc, prod) and want to set up separate cluster managers for each environment. Is it possible to install all of them on a single Ubuntu server, or do we need multiple Ubuntu servers? Thank you

I am going to talk to our System Admin on this... will let you know. **- Okay understood!** As you need to run cluster manager all the time, so it's better to use separate machines. **- Yes the cluster manager needs to run all the time, but why is it better to run it on separate machines if the 3 cluster manager services can run in one server?**

>> but why is it better to run it on separate machines if the 3 cluster manager services can run in one server? We haven't tested this scenario so until we are confident that it will work seamlessly in long run, it will be hard to provide support on such customization.

Okay understood, you let me know when you got feedback from your System Admin about the user session.

Hello Mursel, We just completed a long test ( 2 weeks ) with default cluster-manager installation as user 'root', we haven't faced any issue. >> 1) We have retested and observed that the Ubuntu server performs faster.

Do you have any insights on this issue? i am not sure if i got it correctly.... why Remote desktop client is here? Also.. you are *not* running cluster-manager app as `root` ?

Hey Zico, We have found the issue and it was indeed that we didn't ran the cluster manager as "root". After running as "root" we didn't face any issues.

Got it. Thanks for confirmation!
