FM Repeater - After a week or so, the receive audio is noise on use key up

[KB4MDD]

I have been using the FM repeater mode on my MTR2000 for some time. The FM controller is disabled so that AllStar (app_rpt) performs all of the control over the USRP connection. Everything works great initially. After a week or so, something happens and all inbound RX audio is just noise. Restarting MMDVM Host resolves the issue.

I am using these software versions:

I: 2024-12-09 09:18:55.043 MMDVMHost-20241208_WPSD is running
I: 2024-12-09 09:18:44.949 MMDVM protocol version: 2, description: MMDVM 20221121 12.0000 MHz GitID #029e6df

When it occurred today, I saw this in the log file.

When this happens, the TX audio is still good, but any RX audio is noise. If the user unkeys and keys again, it is still noise. The only way for me to resolve the issue is to restart MMDVM Host.
