Asterisk no response

Version use: Asterisk (1.4.26.3). only use for SIP.

I am doing a 23 channels load test by using asterisk.

I found the Asterisk always no response after several hours running. No response means the extension which I setup in the extension.conf no longer works and if I type “stop now”, the asterisk did not shut donw. I must manually kill the process.

The longest time it works for 17 hours.sometime it works only for 2 hours.

By checking the logs /var/log/asterisk/full, I can not find any logs refer to the asterisk no response.

I am not sure if my configure is not correct. I did get some error log during the starting time of the aserisk

This is the logs during the starting time of the aserisk
