Channel always in state "Stopping"

[elsiomc]

Hi,

I have a Database Reader channel that was stuck at "Stopping".
I've stopped the Mirth process (through task manager) and the dashboard always shows "Stopping" status of the channel.
When I try to halt it, the following error message is displayed: Remove messages task terminated due to error or halt.

[2023-10-02 11:35:42,430] ERROR (com.mirth.connect.server.controllers.DonkeyMessag eController:324): Remove messages task terminated due to error or halt.

Is there any alternative to undeploy the channel from the dashboard?​
The Mirth Connect version is 3.9.0

Thanks

If you halt the channel, you should be able to delete the stuck message and restart the process. Obviously when you delete the message you will lose anything in process.

Thanks for the answer @kirbykn2.
I already done that, but at the dashboard the channel doesn't disappear or stop after halting it.

When I halt the channel two exceptions appear in the server logs:
[2023-10-02 04:31:59,028] ERROR (com.mirth.connect.server.controllers.DonkeyMessageController:324): Remove messages task terminated due to error or halt.
java.util.concurrent.CancellationException

[2023-10-02 04:31:59,028] ERROR (com.mirth.connect.server.channel.ErrorTaskHandler:30): Task cancelled because the channel 72db9d6c-3d4d-4734-b966-733f00b91ee4 was halted or removed.

#3304 is still open. (Also, thanking people "in advance" is a bit of a contentious expression, I would avoid using it entirely. Fun thing to Google.).

Thanks for the feedback @pacmano1 and for the reminder...I apologise for that.
