Hi.
After restarting our server I suddenly get Illegal instruction error after our ec2 instance is launched.
After that the error keeps showing up like illegal instruction. I am not able to start the asterisk process anymore.
I used gdb command and get follow error.
What would be causing this error and how can I avoid this?
