[arm-allstar] Strange Errors, can't reconnect nodes on same Pi

[David McGough]

Hi Matt,

The cause of this issue is probably related to a slow memory leak in the
asterisk software, since everything runs well for many days, finally
reaching a failure point.  You mention 70+ days runtime, then having to
restart asterisk.  Is this a typical, reproducible pattern?

If you're able to catch this problem again, try killing the asterisk 
process with signal 3, which will produce a core-dump, which might help me 
identify the source of the issue.  Here are the steps:

[root at RPi4b-dev ~]# ps -eo pid,etimes,rss,cmd | grep hamvoip | grep -v grep
 5053  932803 57480 /usr/local/hamvoip-asterisk/sbin/asterisk -f -vvvg -c

[root at RPi4b-dev ~]# kill -3 5053

....The core file will get placed in the /var/lib/systemd/coredump/ 
folder.


73, David K4FXC
