Recently I have been having OP25 lock up. I finally pulled the stderr.2, listed below from the point of error. Any help on why it is doing this and how to correct it?
Please let me know if I need to post the entire stderr file text.

Is this gnuradio-3.10 or gnuradio-3.8?
I've seen this error before, but only in gr-3.10 when I was having issues with some not thread-safe behavior. A workaround is easy enough to implement, but on it's own that doesn't explain why digital.fll_band_edge_cc::get_freq_error() is returning infinity.

I did a fresh install on a clean card about 1-2 months ago, so whatever came with the package. How would I check to be sure?

and- of course it's been running fine since I posted the previous message...

I spoke too soon. Locked up again today. Here is what is in the stderr.2 after the last "voice update":

02/01/23 11:56:24.756571 UI Timeout
02/01/23 12:27:24.941039 UI Timeout
02/01/23 12:55:24.911815 UI Timeout
02/01/23 13:26:25.098590 UI Timeout
02/01/23 13:57:25.288754 UI Timeout
02/01/23 14:28:25.477449 UI Timeout
02/01/23 14:59:25.653066 UI Timeout
02/01/23 15:31:24.898535 UI Timeout
02/01/23 16:04:25.228250 UI Timeout
02/01/23 16:39:26.692951 UI Timeout

I am also seeing some PCM Underrun messages. There was an incident going on at the time so I did a quick copy and restart before I could copy the stderr.2 file.

A "UI Timeout" generally occurs after you close the web browser, as a result of rx.py/multi_rx.py noticing the browser is no longer responding to the heartbeat messages. On the one hand it means that the central message dispatcher was still working, but on the other it gets us no closer to knowing which thread became deadlocked.

Next time it happens you might try running top for the rx.py pid.
e.g.
Code: 
ps -ef | grep rx.py
gnorbury  499403  499402 99 Jan30 pts/0    3-18:12:05 /usr/bin/python3 ./multi_rx.py -v 1 -c cfg-test.json
gnorbury  571884    4030  0 18:12 pts/2    00:00:00 grep --color=auto rx.py
gnorbury@yoga2 ~/op25/op25/gr-op25_repeater/apps $ top -H -p 499403

PCM underruns can generally be ignored. They are the result of ALSA audio not filling the buffer quickly enough.
