Summary:                    [patch] Random segfault when querying MySQL via
func_odbc
Description: 
For the past couple months, our two Asterisk servers crash (at different
times) about once a week, and the last entries in the console log are calls
to some of our func_odbc functions. Within the last couple weeks, these
crashes have increased to about every day, sometimes 2-3 times per day.

      Use the sanity check in place of the disconnect/connect cycle.
      
      The disconnect/connect cycle has the potential to cause random
crashes.
