Rick, I've moved recently so you're probably calling my old home number. Send me an email if you need to contact me.
I've not heard of a case of the libraries causing a server crash, and they've had a lot of use both in my own applications and also from the thousands of other developers who have downloaded them from here.
I have seen some issues with the JVM on Domino, none that would cause a server crash, so for a problem like you're having it would probably be best to contact Lotus. You could also try downloading the latest version of the library from here and see if that helps. All versions are backwards compatible.
