[SVN commits to the Asterisk project]

New Revision: 137780

URL: http://svn.digium.com/view/asterisk?view=rev&rev=137780
Log:
If we detect that we are no longer connected, try to reconnect a few times
before giving up.  This relies on the timeout settings in the freetds.conf
file and, unfortunately, on a recent version of FreeTDS (0.82 or newer).

I either need to change the current execs to be non-blocking (which I do
not want to do) or we have to force people to run with the latest and
greatest of FreeTDS.  I'm on the fence...
