The only thing that comes to my head is that the multiplexing socket path could surpass the 108 chars of the sockaddr_un struture passed to bind.

You could try running ssh from the command line enabling the multiplexing feature with different paths, for instance: 

ssh -x2M -S /tmp/mux localhost ls

If that works, you could try with the exact same command executed by Net::OpenSSH. You will be able to see after enabling debug mode on your script: 
$Net::OpenSSH::debug=-1;

Besides that, the other thing that can be done is running ssh under the debugger in order to see what is being passed to bind.

I would do it myself, but have been unable to find any place offering free AIX accounts on the internet.
