I just want to give some tips about debugging those kind of issues. I had
completely different problem which hanged the machine and I needed to debug it.
Since I couldn't access the logs, I setup kernel debugging to remote server. It
is called netconsole. You may want to setup netconsole listener on one of the
working servers outside of your swift, and setup netconsole on the servers that
hang. Here is the information about how to setup:
At least you may be able to see the kernel log just before the machines hang. I
hope you find it useful.
