Your profile may have become corrupted. Try deleting the default.psml for this specific profile and copying the one from psml/user/turbine back in. The NoClassDefFoundError can also be an indicator of the classloader failing because the jvm is running out of resources. This happens in tomcat if you have class re-loading turned on and you are constantly updating classes in your web app. Memory settings of the jvm do not seem to affect this in a noticeable way, at least for me it hasn't.
