> Hi all.
> I have an asterisk server installed with version 16.1.1 on centos 7 Os.
> I have noticed that sometimes my all SIP peers going unreachable including the looping SIP trunk(127.0.0.1) which I have. I was checking for the locks in asterisk using asterisk -rx “core show locks” and below is my result.
