I've been trying to crack this problem for a while now, with no luck.

I get inconsistent occurances of the "Class Definition X is not found." error in various places within my application.

It isn't a specific process that causes the error, because I can perform the same operations 10 times and it will be fine, then another time I can get the error doing the exact same operation only once.

To try and help me debug this, I've got the application dumping all kinds of info when this error occurs, i.e. variables being used, etc..

What I've found is, the "SET CLASSLIB" value is being "mangled" (for lack of a better word)

For example I have a couple of dozen classes loaded in memory and when this error occurs, the classes in "SET CLASSLIB" have the wrong aliases assigned to them.

Some have the same alias repeated over several different classes, others appear to have aliases resembling variable names being used in the process where the error occured.

Has anyone else run into this?

What is the cause and how can I rectify the situation?

Thanks for any input,

- Aaron.
