openssl, verify error

Hallo,
Could someone help me out with the following problem:

We use www-lib and openssl, server and client authentication. If the server
certificate can't verify openssl traces "verify error: num=19 ... ".
In this case the application can't trust the server and should terminate,
but the application runaway. Is there any possibility by configuration to
stop the the application?

Thanks
D.Baum
