Are you sure that the errors are really going away?  It just looks like
you're turning off exceptions, and now hiding the potential connection
errors.

Some questions that might help track down the problem:

Are you connecting each of those connections manually?

Can you get data from each connection?  Is there a time delay that might
cause all those connections to timeout?  What does your code do when timeouts
occur?

Is this a multi-threaded app?

(btw, this has nothing to do with new/delete... as you mentioned, it should
work either way)
