Steps to reproduce

1. Choose a site -> Configuration -> Site Settings -> General tab -> Site URL section
2. In Public Pages input and/or Private Pages input a string of any length can be entered (i.e. longer than Virtualhost.hostname column definition)

Observed result

Entered data can not be managed by system and an exception is thrown:

An error message is showed:
Portlet is temporarily unavailable.

Expected result
A max length validation should be used with this value, similar to
Control Panel -> Configuration -> Instance Settings -> Configuration tab -> Virtual Host input
