Oh it is a problem, and most handle it very ungracefully, such as dovecot which just dies:

The issue is also most people are used to using rc.local or rc.* type scripts to spawn a daemon which leads to the next major sysadmin/developer problem with is handling error cases improperly or not at all.  (86401 is perhaps and error case that people should test for).
