Usually this is caused by referencing a piece of memory in a native method that hasn't been initialized yet or has already been freed.
Is this in native code you have written, or is it in a third party DLL? If it is the first, you'll have to check where the problem is in your native code. Printing debug information usually helps me. If it is a third party DLL then first check if you aren't violating the contract of its API (like passing null where it isn't allowed). If you don't, contact the creators.
Looks like it's the JDBC/ODBC bridge, which is simply not meant for production work. It's a buggy mess. What you need to do it to obtain the real driver for your database. If your database is Access, then you need to use a real database for an application that's serving this many clients!
