Yea, I missed the forked call to the bind. It's here:

Nothing stands out to me as a possible previous error that might be causing the bind error. I did see the following repeating error in another process that may also be related: 

477272: kioctl(3, 22528, 0x0000000000000000, 0x0000000000000000)113710

Seems like that'd be expected though since ssh is being run through a Perl module.

Permissions on .libnet-openssh-perl are set to 700.
