Exception: java.lang.IndexOutofBoundsException

[MarshBruce]

I am repeatedly receiving the following message when I attempt to rescan and it has made my MinimServer inoperative. Please advise.

Exception while processing action request: java.lang.IndexOutOfBoundsException: Index: 5451, Size: 5451

Please copy and paste the full stack trace into a post here. You can find this in the MinimServer log (click Show log from the minim icon).

Thanks for this. It looks like your control point might be accessing the list of folders while it is changing (or has changed very recently) because of a rescan. Which control point are you using?

[MarshBruce]

I recently did change my folders but was unable to change the content directories in MinimServer as it did not give me a GUI, only a text of status, so no way to delete or add content directories to reflect the folder changes.
I do not know what a "control point" is, so I cannot reply to your question. MinimServer is working in Synology.

I do not know what a "control point" is, so I cannot reply to your question. MinimServer is working in Synology.

The control point is the GUI that you use to browse your library and select music to play. How are you doing this?

On Synology, you can show the MinimServer web page by clicking on the MinimServer icon in the Synology DSM main menu or by clicking Open from the MinimServer icon in the Synology Package Center. This allows you to set and change a single content directory. To set more than one content directory and enable other diagnostic and configuration settings, you should install MinimWatch on another computer in your local network. See this section for details.

[MarshBruce]

I use both in Synology, I click on the MinimServer icon in the Synology DSM main menu and I click Open from the MinimServer icon in the Synology Package Center. Both bring up text of status page that does not allow me to alter the content directories.

[simoncn]

Because you have set multiple content directories using MinimWatch, you cannot change these directories from the status page. You need to change these directories from MinimWatch.

To make progress with solving this problem, I need to know what control point you are using. The control point is the GUI that you use to browse your library and select music to play. How are you doing this?

[MarshBruce]

In Synology, I go to File Station and then select a directory that the music may be in. That works.

(I also use Naim app that shows MinimServer, and when I select that, it will show me the content directories (the older ones before the changes).

I hope I am being responsive to you inquiry

[simoncn]

It sounds like your control point is the Naim app. Do you have the Naim app running when you do a rescan and get the error message? If so, please try powering off the device that is running the Naim app and do the rescan again.
