app_read.c needs some "help"

I have several 1.4 installs running and now one of my systems that gets 40K calls per month is suffering because the default behavior of disconnecting on an error. They will go a few hundred calls with no problems, then “wham” - mystery disconnect because app_read failed and disconnected without a warning. I’d really like a working patch for 1.4 instead of upgrading them to 10.0. Any thoughts?
