Sporadic Disconnections

Hi there,

I seem to be having issues where asterisk seems to restart, in turn disconnecting every device registered to it for a second. This is causing any calls that are connected to also disconnect.
There have been no new software updates or any changes to the dialplan code. I thought it may have been an issue at network level and investigating into that has shown that there are no network problems causing this.
I have then looked into the linux message logs and can see the error below which happens at the same time there is a disconnection. Looking up this error I cant really see much resource as to what the cause is or how to resolve it. Does anyone have any experience of this that they could share?

Asterisk asterisk-16.6.2
Centos 7

It crashed in chan_pjsip for some reason. That’s the most that can be said, and you’re also running over a 2 year old version which means the underlying issue may have already been fixed.
