Bug Fix: Upgrade default freetds verion plz.

My Web Service sometimes error message "SQLSTATE[01002] Adaptive Server connection failed (severity 9)"

I saved it to a log file when connection an error occurred. (Error time, Error Url, Error message)

0.5%~ 1% connection error occurs.

I view freetds changelog file and upgradep freetds 1.00.44 version.

then error never occur for 3 months.

So, Please upgrade default freetds version.
