I am building an Asterisk server using an ec2 instance from the Amazon AWS Service.
Now I have the following problem.

I need to say, this only occurs sometimes, not always!

When I create an instance through the Amazon Cli AMI, it works in most of the cases, but sometimes I get the error "Illegal Instruction".

```
# asterisk -cvvvvvvvvvvvvr
Illegal Instruction

```

When this occurs, the programs like Asterisk don't work. 
I try restarting the processes, but the error "Illegal Instruction" keeps showing up.

How can I avoid this? 
Is this an error that more people have with the Amazon Cli AMI.
Any suggestions would be highly appreciated. 

Thank you
