Description of Problem
After upgrading the iMac to Catalina Roon freezes on the iMac. You can´t start Roon by clicking on the Roon icon. The only way is to restart the iMac, which is not the way it should be.
Hi there, I attached scrennshuts which show cpu activity (pic 1 and 2) In pic 3 you can see that I made upgrade to catalina 10.15.1 (released today in germany)
The next 2 pictures show cpu activity after updating.
So maybe the issue is being fixed with the catalina update. Ronn works fine and stable since august this year. The only thing which realy changed was the catalina update.
Roon starts automatically because I choosed this option. Everything works fine then but after a certain time (half an hour one hour I don´t know) roon freezes on the imac. The only way to get it back to work was to press the on/off button on the imac.
Meanwhile I installed the catalina update 10.15.1, which helped a bit. But still there are some issues, for example yesterday ronn worked fine for hours but in the late afternoon there was suddenly no core available on the ipad pro and roon was not working on the imac. You cańt close and restart roon then, means you have to shut down the imac by pressing the on/off button and restart the imac and roon.
So this morning Íll follow the latest instructions you gave me.
Thanks for sending that crash report over, I can confirm I received it an it will be useful if we need to troubleshoot this issue further. Has there been any change in behavior since starting Roon fresh, does it still freeze?
thanks for the additional feedback, I´ll do how suggested.
But at the weekend my imac crashed and not only roon didn´t work properly but the same with other programs/apps.
I could´t even start the imac properly. In recovery mode I couldn´t relaunchCatalina OS because of missing space. And I think this was the reason why! After the update to Catalina the fusion drive of the imac had almost 1,0TB used which means almost 100% of the available space.
Know I´m deleting things to get space and this keeps me busy at the time. I bought a samsung ssd with1,0TB for the foto library which means I´ll have 50% of the fusion drive free.
Roon works a bit slow at the moment, but I guess it´s because the imac cpu is busy.
By the way I´m thinking in buying a synology 718+ nas with 6GB RAM and 240 GB ssd for the roon server. Could you recommend this stuff?
Sorry when I kept you busy with a stupid problem but I wasn´t able to recognize it.
Thanks for the update here and glad to hear you’ve been able to narrow down the issue to the amount of free space on your drive!
Yes, if you’re currently moving those files over, this is what could be causing Roon to operate slowly for the time bing. Once the transfer is complete, I would reboot and check to see how things are working.
No, I would not recommend this model. From the Amazon page, it looks like this NAS is running a Intel Celeron J3455 Quad-core 1.5 GHz, which is below our Minimum Requirements.
Personally, I would suggest that you either build or buy a Roon ROCK system, a dedicated linux-based server (that meets our minimum requirements). You can find out more information on this here: https://kb.roonlabs.com/ROCK:_Getting_Started
Sorry, but it´s me again. Roon freezes again on the imac (OS 10.15.2, latest roon). Yesterday I noticed a retarded reaction (change from album to overview on the ipad pro took a couple of seconds, normaly it less than a second i.e.)
I tried a macbook pro (late2011 with 8GB RAM and 500GB Samsung SSD) instead, but reaction time with the imac is better, faster.
I attached a link to the log files above: Frank_Schulze1.zip
Thanks for sending those logs over, but it appears that the download link unfortunately expired. In either case, I don’t think the logs would help much because you mentioned something else above:
It sounds like something hardware-related is going on with your iMac. If the other apps were crashing as well and Roon was still unstable after getting the new drive, I would consider running a disk check on the iMac.
It’s also possible that the Roon database on the iMac is not intact anymore (if Roon was trying to write something to the database and didn’t have enough space for example). If you can confirm you have enough free space and want to give Roon on the iMac another try, you can set your old database aside by using these instructions (on the iMac, not the Macbook):
Restart/Reinstall the Roon App to generate a new Roon folder
If you are happy with using the Macbook pro as the Roon Core, you don’t have to perform the above instructions, it’s only needed if you want to take a look at the iMac again as the Roon Core after resolving the hard drive issues.
