Running FreePBX 14.0.11 / Asterisk 13.27.0 on a Raspberry Pi (just a few concurrent calls) using the RasPBX image.

Here’s a snippet of the logs where the system restarts:

Any thoughts on what the issue is or how I can go about troubleshooting?


#2

Your memory was corrupted at 2019-07-09 20:23:40, asterisk restarted, What Pi? You might be stretching things on any Pi as both FreePBX and Asterisk get more greedy as they develop

Do you have a swap device and where is it located?


(Andrew Ferguson) #3

It’s a Raspberry Pi 2 Model B.
Swap is using /dev/zram0 to /dev/zram3 for a total of ~214MB.


#4

Install sysstat , it will studiously keep a log by hour of ‘things that get stressed’ after you enable it in

apt-get install -y sysstat
nano /etc/default/sysstat

after an hour or two

sar -A

will help your diagnostics

If asterisk crashed /var/log/messages might give a clue at that time
