Sybase SQL Anywhere driver throws NullReferenceException

I have the problem, that in my multithreading application, the SQL Anywhere 12 driver throws NullReferenceExceptions. The Exception is always thrown at different points, but always during opening a connection. There are a maximum of 5 open connections. The stack trace is the following:

enter image description here

I have no idea why this happens.

Does anyone else has similar problems? Currently i have no idea.

EDIT:

The error is not really reproducible, because some times the app runs correct for two hours or a day and some times only 10min.

Well, the SAConnectionPoolManager were not thread safe when multiple threads are trying to allocate/close multiple connection pools. This was fixed (so they say) in version 16.0.0.1431 and 12.0.1.3851.
