Steven,

  If you are using a hostname for an ITSP and DNS fails, it will take
FOREVER for the SIP channel driver to load/reload/do anything that
requires a DNS lookup.  This will in some cases block the rest of
Asterisk but will certainly make anything that depends on SIP break -
until the DNS request finally fails.

  I have started a new thread on -dev about this...
