Asterisk app_mixmonitor.c crash

Dear.

I have asterisk version 13.38, and asterisk crashed twice, and the only log I can find is this

app_mixmonitor.c: Unable to add ‘MixMonitor’ spy to channel

Could you please explain what this error would be and how to fix it if possible!

Thank you, hugs!

This message shows no evidence of a crash.

The most likely causes are failures in ast_audiohook_attach, which seem to come down to either trying to do it on a channel that has already been hung up, or trying to do it when there is a critical shortage of memory. The latter is likely to result in many other errors.

If it were crashing, you would need to upgrade to Asterisk 18 or 20, before progressing the issue, as Asterisk 13 is over a year beyond end of life.

possibly that’s it, because I can’t find the channel specified in the message in the logs!

app_mixmonitor.c: Unable to add ‘MixMonitor’ spy to channel ‘SIP/discador-00019868’
