Only close server when errno is not EINTR

[rowandempster]

Solved Problem

When I try to run a startup script I found that the system() call for that startup script was triggering a daemon server error that shuts down the socket early. Looks like another developer had handled this case by trying to ignore the specific errno for that system() triggered error, but left the break of that socket while loop outside of that errno check.

Solution

Moved break into the if errno check

To be honest I don't understand the details here. WOuld need to start from scratch. Let's see if @julianoes or @bkueng have the context.
